Manage Forms
How to use the form builder: add fields, descriptive text and brand new fields, choose where each one goes, change labels and make fields required, drag fields into order, set up Dynamic Workflow Triggers, choose the style, workflow, autoresponder, redirect and spam protection, and share the form by link, embed code or form source.
On this page
The form builder is where you put a form together. It holds everything about one form on a single page: the fields a visitor fills in, the settings that decide what happens when the form is submitted, and the link and code for putting the form in front of people.
You build the form by clicking. Pick a field from a list and it lands on the form. Click a field on the form to change its wording. Drag a field to move it. The form is drawn in front of you the whole time, so you always see what you are making.
To get here, go to Settings, click Forms, and click the name of a form.
The forms, fields and workflows in these pictures are examples. If your account calls Forms something else, you will see that name on the first button of the toolbar.
Building a form, start to finish
If you just want a working form, these are the steps. Each one is explained in full further down.
- On the Forms page, click Add Form, give the form a name, and click Create and open. The builder opens with an empty form.
- In the Add a field list on the right, click each field you want. Start with First Name, Last Name and Email.
- Click a field on the form to change its label or to make it required. Click Save field.
- Drag fields by their handle until they are in the order you want.
- Open the Settings tab. Choose a style for the look, a workflow to start for each new lead, and turn on spam protection.
- Click Preview in the toolbar to see the real form.
- Open the Share tab and copy the link, or the code for your website.
The page at a glance
From top to bottom, the page has four parts:
- The toolbar – go back to the list of forms, preview the form, duplicate it, delete it, or open Help.
- The top card – the form’s name, whether it is a Primary or an Update form, and a line of numbers about it.
- Three tabs – Fields, Settings and Share.
- The work area – whatever the tab you chose holds.
The toolbar
| Button | What it does |
|---|---|
| Forms | Goes back to the list of forms. |
| Preview | Opens the real form in a new browser tab, exactly as a visitor sees it. See Previewing the form below. |
| Duplicate | Makes a copy of the form and opens the copy. See Duplicating a form below. |
| Delete | Deletes the form, after asking you to confirm. See Deleting a form below. |
| Help | Offers a short guided tour of the page, or opens this guide. |
The name, the kind of form, and the numbers
To rename the form: Click the name, type a new one, and press Enter or click anywhere else. Press Esc to put the old name back. A name can be up to 100 characters and cannot be left empty.
Visitors see the name as the heading of the form, unless the form’s style has a header of its own, such as a logo. Choose a name you are happy for them to read.
Primary and Update set what the form does. A primary form creates a new lead each time it is submitted. An update form changes a lead you already have. Click one to switch; the change is saved at once. See Primary and update forms below.
The line under the name is a quick summary of the form:
| You see | What it means |
|---|---|
| 15 fields | How many fields and pieces of descriptive text are on the form. |
| 128 submissions | How many times the form has been sent in. |
| Last: 3 hours ago | When the most recent lead came in through the form. Hold your mouse over it for the exact date and time. |
| Created Mar 7, 2025 | The day the form was made. Hold your mouse over it for the time as well. |
| 43 blocked as spam | How many submissions spam protection has stopped. Hold your mouse over it to see how many were stopped by IP address and how many by the Honeypot. It is only shown once something has been blocked. |
| Private | With a padlock. The form has no public link. It is only shown on private forms. |
The three tabs
| Tab | What is in it |
|---|---|
| Fields | The form itself. Add, change, move and remove fields here. The number in brackets is how many are on the form. |
| Settings | The description, style, workflow, autoresponder, redirect, spam protection and a few other switches. |
| Share | The link to the form, the code for embedding it in your website, and the form source for web designers. |
How saving works
There is no Save button for the whole page. Each kind of change is saved on its own, and a green message at the top right of the page confirms it.
| What you change | When it is saved |
|---|---|
| The name, Primary or Update, and everything on the Settings tab | As soon as you change it. |
| The order of the fields | As soon as you drop a field in its new place. |
| Adding or removing a field | Straight away. |
| A field’s label, its Required switch and its Dynamic Workflow Trigger | When you click Save field. If you move on to another field without clicking it, your changes are saved for you first. |
While a field has changes that are not saved yet, the words Unsaved changes show in orange at the top of the panel. If something is wrong with them, for example a rule with no workflow chosen, a red message tells you what to fix and you stay on that field until it is put right.
If you try to leave the page while a field has unsaved changes, your browser asks whether you really want to leave. Stay on the page and click Save field to keep your work.
The Fields tab
The Fields tab has two halves. On the left, under Your form, is a sketch of the form with every field in order. On the right is a panel that does two jobs: it is the list you add fields from, and when you click a field on the form it becomes the place where you change that field.
Reading the sketch of your form
The sketch shows what a visitor gets, from top to bottom:
- The top of the form. The heading is the form’s name, with your account name above it when the form has no style. If the form’s style has a header of its own, such as your logo, that is shown instead. Your description, if you wrote one on the Settings tab, is shown here too.
- First Name and Last Name. These two are always printed side by side at the top of the form.
- Every other field. One after another, in the order visitors will see them.
- The bottom of the form. The robot check, if one is turned on, and the button, with the wording and color its style gives it.
Each field carries a few markers:
| Marker | What it means |
|---|---|
| The six dots on the left | The handle. Drag it to move the field up or down. |
| A red * after the label | The field is required. A visitor cannot send the form without filling it in. |
| The grey tag on the right | The kind of field: Text, Dropdown, Checkbox and so on. |
| An orange tag with a lightning bolt | The field has a Dynamic Workflow Trigger, and this is how many rules it has. |
| The X on the right | Takes the field off the form, after asking you to confirm. |
| A box with a dashed border | A hidden field. Visitors never see it. The sketch shows the value it sends. |
| “and 2 more” | A long list of choices is cut short on the sketch to save room. The real form shows them all. |
The sketch is a drawing, so you can work quickly. It leaves out some of the fine detail of the real page, such as the exact fonts. Click Preview to see the real thing.
The kinds of field
Every field has a type, which decides what a visitor is given to fill in. The type belongs to the field and is chosen when the field is created.
| Type | What the visitor gets |
|---|---|
| Text | A box for one line of letters and numbers. |
| Text Area | A taller box for sentences and paragraphs. |
| Number | A box that only takes a number. |
| Currency | A box for an amount of money, with a $ in front of it. |
| Date | A box that opens a calendar. |
| Checkbox | One box to tick, for yes or no. |
| Checkbox Group | Several boxes. Any number of them can be ticked. |
| Dropdown | A list that opens. One choice can be picked. |
| Radio Buttons | A list with every choice in view. One choice can be picked. |
| URL | A box for a web address. |
| Hidden | Nothing. A hidden field sends a value you set in advance, for your own use. |
| Descriptive text | Not a field at all, but wording you place between fields: a heading or a line of instructions. |
Adding fields
When no field is selected, the panel on the right reads Add a field and lists every field you can still put on the form.
- General fields are the standard details every lead has: name, email, phones, employer, job title and addresses.
- Below them are your own fields, grouped by category the same way they are on the Fields page. Fields with no category are listed under Other fields.
- The number next to each heading is how many fields are in that group. Click a heading to fold the group away, and click it again to open it.
- Each row shows the field’s name and, on the right, its type.
To add a field, click it. The field goes on the form, a green message confirms it, and the new field is highlighted for a moment so you can see where it went.
A field can be on a form only once. As soon as it is on the form it leaves the list, and it comes back if you remove it from the form. When every field you have is on the form, the list says so.
Finding a field
Type part of a name in Search fields and the list narrows as you type. Clear the box to see everything again.
Choosing where the next field goes
A new field normally goes to the end of the form. To put it somewhere else:
- Point at the field you want the new one to sit under. A round + appears at its bottom edge.
- Click the +.
- Click the field you want in the list.
After you click the +, a dashed line on the form reads The next field you add goes here, and a note at the top of the panel names the field the new one will go under.
- The marker moves down after each field you add, so several fields added one after another stay in the order you clicked them.
- There is also a round + just under First Name and Last Name. Use it to put a field at the very top of the list.
- To go back to adding at the end of the form, click Add at the end instead on the marker, or Add at the end in the panel.
Adding descriptive text
Descriptive text is wording that sits between fields. Use it for a heading that splits a long form into parts, or for a line of instructions above a question.
- Click Descriptive text at the top of the Add a field panel.
- A block of text is added to the form and opened in the panel, ready for you to type.
- Type your wording in Text. The sketch changes as you type.
- Click Save field.
You can add as many pieces of descriptive text as you like, and move and remove them the same way as fields.
For anything fancier than plain wording you can use simple HTML in the text, such as for bold.
Creating a brand new field
If the field you need does not exist yet, you can make it without leaving the builder.
- Click New field at the top of the Add a field panel.
- Type a Name. This is the field’s own name, used on leads and in reports. It can be up to 50 characters.
- Choose a Type. A line under the box explains each type as you choose it.
- For a Dropdown, Radio Buttons or a Checkbox Group, type the Choices, one per line. Each choice needs its own wording.
- For a Hidden field, type the Value it should send.
- Choose a Category, if your account uses field categories.
- Click Create and add.
The field is created in your account and placed on the form in one step. From then on it is an ordinary field: it appears on the Fields page under Settings, it can be used on your other forms, and leads keep whatever is entered in it.
The New field button is only shown to people who are allowed to add or manage fields. To change a field’s choices later, or the value of a hidden field, use the Fields page under Settings.
Changing a field
Click a field on the form. It is outlined, and the panel on the right switches from the list to that field.
At the top of the panel are the field’s own name and its type, and whether it is a General field or a Custom field, meaning one of your own. Below that are the things you can change for this form.
| Setting | What it does |
|---|---|
| Label | The wording visitors see next to the field. It starts out the same as the field’s name, and you can change it to anything up to 100 characters, for example a full question. Changing the label does not rename the field: leads and reports keep using the field’s own name. |
| Required | When this is on, the form cannot be sent until the field is filled in, and a red * is shown after the label. |
| Choices | Shown for a Dropdown, Radio Buttons and a Checkbox Group. The choices belong to the field, so they are the same on every form. To change them, click Change them on the Fields page. |
| Dynamic Workflow Trigger | Starts a workflow when the visitor’s answer matches a rule. See Dynamic Workflow Triggers below. |
The sketch follows along while you type, so you can see how the label will look before you save it.
When you are done, click Save field. Pressing Enter while you are typing in the Label box does the same. To go back to the list of fields, click Add fields at the top of the panel.
| Button | What it does |
|---|---|
| Save field | Saves the label, the Required switch and the trigger rules of this field. |
| The up and down arrows | Move the field one place up or down the form. |
| Remove | Takes the field off the form, after asking you to confirm. |
First Name and Last Name
On the real form, First Name and Last Name are always printed side by side at the top, wherever they are in the order. The sketch shows them the same way, without a handle, and the panel reminds you when you select one of them. You can still change their labels, make them required, and remove them.
Hidden fields
A hidden field is never shown to visitors. It quietly sends the same value with every submission, which is handy for marking where a lead came from. On the sketch it is drawn in a dashed box together with the value it sends.
A hidden field has a label only so that you can recognize it. It cannot be required and it cannot have a trigger. To change the value it sends, click Change its value on the Fields page.
Moving fields
There are two ways to change the order:
- Drag. Press on the six dots at the left of a field, drag it up or down, and let go where you want it. A green message, Order saved, confirms the new order.
- Use the arrows. Click a field, then use the up and down arrows at the bottom of the panel to move it one place at a time. This is the easy way on a phone or a tablet.
The order on the sketch is the order on the real form. First Name and Last Name are the exception: they stay at the top, so they have no handle and their arrows are greyed out.
Removing a field
- Click the X at the right of the field, or select the field and click Remove at the bottom of the panel.
- Read the message, then click Remove to go ahead or Cancel to keep the field.
- Removing a field only takes it off this form. The field itself stays in your account, and every lead keeps what was entered in it.
- The field goes back into the Add a field list, so you can put it on the form again later.
- If the field had a Dynamic Workflow Trigger, its rules are deleted. The message tells you how many.
- Removing a piece of descriptive text deletes its wording.
Dynamic Workflow Triggers
A Dynamic Workflow Trigger starts a workflow because of what a visitor answered. For example: when someone picks the highest price range, start the workflow that alerts your senior salesperson. When someone ticks Golf, start the workflow that sends your golf newsletter.
It works alongside the form’s own workflow, which you choose on the Settings tab under Apply workflow. The form’s workflow starts for every lead that comes in. A trigger adds another workflow for the leads whose answer matches.
Setting up a trigger
- On the Fields tab, click the field whose answer should start the workflow.
- In the panel, under Dynamic Workflow Trigger, turn on Start a workflow when this field matches a rule. The first rule appears.
- After If it, choose the comparison, such as is or contains.
- Fill in what to compare the answer with. Depending on the field, this is a box to type in, a list of the field’s choices, or a date.
- After start, choose the workflow.
- To add another rule, click Add rule. To take a rule away, click the bin at its right.
- Click Save field.
Read a rule from left to right, like a sentence: If it is greater than 300000, start Website Request Information Follow Up.
Once the trigger is saved, the field carries an orange tag on the sketch with a lightning bolt and the number of rules, so you can see at a glance which fields start workflows.
How the rules are checked
- The rules are checked when the form is submitted.
- Each rule is checked on its own. Every rule that matches starts its workflow, so one answer can start more than one workflow.
- A field can have up to 50 rules.
- The form’s own workflow cannot be chosen in a rule, because it already starts for every lead. It is greyed out in the list and marked already the form’s workflow.
- Text is compared exactly as it was typed, including capital letters. “Golf” and “golf” are not the same.
The comparisons for each kind of field
The comparisons you are offered depend on the type of field.
| Type of field | Comparisons | What you compare with |
|---|---|---|
| Text | contains, does not contain, starts with, is, is not, is empty, is not empty | Words that you type. |
| Text Area | contains, does not contain, is empty, is not empty | Words that you type. |
| Number and Currency | is, is not, is empty, is not empty, is greater than, is less than, is greater than or equal to, is less than or equal to | A number that you type. |
| Dropdown and Radio Buttons | is, is not, is empty, is not empty, and the four greater than and less than comparisons | One of the field’s choices, picked from a list. The greater than and less than comparisons only make sense when the choices are numbers. |
| Date | is, is not, is empty, is not empty, is after, is before | A date, picked from a calendar. |
| Checkbox | is checked, is not checked | Nothing. |
| Checkbox Group | is checked, is not checked | The box you mean, picked from a list. |
| URL | is, is not, is empty, is not empty | A web address that you type. |
is empty and is not empty need nothing to compare with, so the second box disappears when you choose one of them.
Hidden fields and descriptive text cannot have a trigger.
Switching a trigger off
Turn off Start a workflow when this field matches a rule and click Save field. The workflows stop being started, but the rules are kept, so you can switch the trigger back on later without setting them up again. A note under the switch tells you how many rules are being kept.
When a rule cannot be saved
If something is missing, a red message at the top of the panel says what, and nothing is saved until it is put right.
| Message | What to do |
|---|---|
| Choose a workflow for every rule. | Pick a workflow in the start box of each rule. |
| Every rule needs something to compare with. | Fill in the empty box of the rule, or delete the rule. |
| The rule needs a number to compare with. | A greater than or less than comparison was given something that is not a number. Type a number. |
| Add at least one rule, or switch the trigger off. | The trigger is on but has no rules. Click Add rule, or turn the switch off. |
The Settings tab
The Settings tab holds everything about the form that is not a field. Each setting is saved the moment you change it. There is no Save button; watch for the green Saved message.
For a box you type in, such as the description, the setting is saved when you click somewhere else on the page.
Look and wording
| Setting | What it does |
|---|---|
| Description | A few words shown at the top of the form, above the fields. Leave it empty if you do not need it. |
| Style | The look of the form: its logo, colors, font and button. Choose one of your styles, or No style (the standard look). A small picture next to the box shows the style you chose. Click Edit this style to open it in the style editor, or Manage styles when no style is chosen. |
| Remove the form header | Leaves out the heading printed at the top of the form, which is your account name and the form’s name. You do not need this when the style has a header of its own, because that header already takes the heading’s place. |
When the form is submitted
| Setting | What it does |
|---|---|
| Apply workflow | The workflow started for every lead that comes in through this form. Choose None for no workflow. To start a different workflow for particular answers, use a Dynamic Workflow Trigger on the Fields tab. |
| Autoresponder | A message from your message library that is sent automatically when the form is submitted. The messages are listed by category. |
| Redirect to | The web page visitors are sent to after they submit, such as a thank-you page on your website. Type the full address. If you leave off the https:// at the front, it is added for you. A redirect does not work when the form is embedded in a frame on your website. |
Spam protection
| Setting | What it does |
|---|---|
| Robot check | A test a visitor passes before the form can be sent. reCAPTCHA shows the familiar “I’m not a robot” box and is the one to choose for most forms. CAPTCHA is the older check, where the visitor types the characters shown in a picture. None turns the check off. Only one can be on at a time. |
| Honeypot | Adds hidden fields that only robots fill in. Visitors never see them, and a submission that fills them in is ignored. It can be used together with a robot check. |
| Spam monitor | How many submissions have been blocked so far, by IP address and by the Honeypot. |
A public form with no robot check and no Honeypot is open to spam. Turn on at least one of them for every form you put on a website.
Forms hosted on your own website. If a web designer has copied the form’s code onto your own website, instead of using the link or the embed code, click Is this form’s code hosted on your own website? to open the extra settings:
- External form domains – the domains the form is hosted on, one per line, without http:// or https://. reCAPTCHA needs at least one domain here to work on your own website. Anything that is not a domain name is left out when the list is saved, and the message tells you.
- After turning on reCAPTCHA or the Honeypot, the code on your website has to be updated. Click view the form source for the whole form, or just the honeypot code for only the Honeypot part.
- The box at the bottom holds the reCAPTCHA code. Your designer places it where the check should appear.
Incoming leads
| Setting | What it does |
|---|---|
| Auto group incoming leads | Groups a new lead with the leads you already have under the same email address. |
| Assign auto group primary user | Gives every auto grouped lead to the primary user of its group. It can only be turned on while Auto group incoming leads is on. |
| Lead following | Turns on following for every lead that comes in through this form. |
| Auto archive exclude | Leaves the leads from this form out when duplicate leads are archived automatically. |
Who can use it
| Setting | What it does |
|---|---|
| Private | A private form has no public link, so it cannot be shared or put on a website. The top card shows a padlock, and the Share tab tells you the form is private. |
| Hide from lead add | Leaves this form out of the forms offered when someone on your team adds a lead by hand. |
The Share tab
The Share tab is where you collect what you need to put the form in front of people.
| Card | What it gives you |
|---|---|
| Link to this form | The form’s own web address. Click Copy to copy it, then paste it into an email, a social media post, or a link on your website. Click Open to see the live form in a new tab. |
| Embed it in your website | A piece of code that shows the form inside a page of your website. Click Copy and paste the code into the page. Change height="700" until the whole form fits; once it does, you can set scrolling="no" to hide the scroll bars. |
| Form source, for web designers | The HTML and JavaScript of the form, for a designer who wants to build the form into your website and post the answers to Open Leads. Click View form source. A form hosted this way needs its domain listed under Spam protection on the Settings tab. |
| See it first | Another way to open the preview. |
Clicking in a box of link or code selects all of it, in case you prefer to copy it yourself.
The link and the embed code always show the form as it is now. When you change the form here, the form on your website changes with it. A form built from the form source is different: it is a copy on your website, so it has to be updated by your designer when you change the form.
A private form has no link to share. The Share tab says so, and offers a button that takes you to the Private switch.
Primary and update forms
| Kind | What it does | How people reach it |
|---|---|---|
| Primary | Creates a new lead each time it is submitted. Most forms are primary forms. | Through its link, or on your website. |
| Update | Changes a lead you already have. Use it to let a lead correct their details or tell you more about themselves. | Through a personal link in a message you send them, so the answers go to the right lead. |
To switch, click Primary or Update on the top card. The line under the name explains the kind you chose.
For an update form, the Share tab changes. In place of a public link it shows how to send the form to a lead:
- In the message editor, click Update Form Link and choose the form. This is the easy way.
- Or click Copy to copy the link shown on the Share tab, paste it into your message, and change the words “My Link To Form” to whatever the link should say.
- The message can be sent from a lead, in a mass email, or by a workflow as an autoresponder.
Previewing the form
Click Preview in the toolbar, or under the sketch, to open the real form in a new browser tab. This is exactly what a visitor sees, with the form’s style, so it is the place to check the look, the wording and the order before you share the form.
- Everything you change in the builder is already saved, so the preview is up to date. If a field still says Unsaved changes, click Save field first.
- Leave the preview tab open while you work, and reload it to see your latest changes.
- Try it on your phone as well. The form fits itself to a small screen.
To test the whole journey, open the form from its link on the Share tab, fill it in and send it. A real lead is created, so you can check that the lead arrived and that the right workflow started.
Duplicating a form
When you need a form that is nearly the same as this one, click Duplicate in the toolbar. A copy is made and opened straight away, with (Copy) added to its name.
- The copy has the same fields and the same settings as the original.
- It gets its own link, and its submissions start at zero.
- Rename it at the top of the page, then change whatever needs to be different.
- If a field on the original uses a Dynamic Workflow Trigger, open that field on the copy and set its rules again.
Deleting a form
- Click Delete in the toolbar.
- Read the message. It tells you what will stop working and how many submissions the form has had.
- Click Delete to go ahead, or Cancel to keep the form.
Deleting a form cannot be undone. Its link stops working, and so does any copy of the form on your website. For an update form, any message that links to it stops working.
Who can use the form builder
The form builder needs the Manage Forms permission. Creating a brand new field from the builder also needs permission to add or manage fields; without it, the New field button is not shown. If you need either one, ask your account administrator.
On a phone or a small screen
The builder works on a phone or a tablet. The two halves of the Fields tab are stacked: the form comes first and the panel moves below it.
- Tap Add a field at the top of the form to jump down to the list of fields.
- Tap a field to open it in the panel. The page moves down to the panel for you.
- The round + under each field is always in view, because there is no mouse to point with.
- Use the up and down arrows in the panel to move a field. They are easier than dragging on a touch screen.
Help and the tour
The Help button at the right of the toolbar has two choices:
- Take the tour walks you through the page in about a minute. It points at each part in turn and explains it.
- Open the help guide opens this guide.
Use Next and Back to move through the tour, or the X to leave it. You can take it again at any time.
The first time you open the builder, a small note offers you the tour. Click Take the tour to start it, or Don’t show again if you would rather not be asked again.
Tips
- Keep forms short. Every extra field is a reason for a visitor to give up. Ask for what you need now, and use an update form later to learn more.
- Only make a field required when you truly cannot do without it. Email is usually the one that matters.
- Write labels the way you would ask the question out loud. “When would you like to move in?” reads better than “Move-In Date”.
- Split a long form into parts with descriptive text, such as “About you” and “About the home you want”.
- Use a Dynamic Workflow Trigger to send the right follow-up to the right lead, instead of building a separate form for each kind of lead.
- Add a hidden field to mark where leads came from, such as “Spring mailer”, without asking the visitor anything.
- Turn on reCAPTCHA and the Honeypot for every form on a public website.
- Before you share a new form, look at it with Preview, then send one test submission through its link and check that the lead arrived and the right workflow started.
- To try out a big change safely, duplicate the form and work on the copy.
Questions and answers
A field I want is not in the Add a field list.
Check whether it is already on the form: a field can be on a form only once, and it leaves the list once it is added. If the field does not exist yet, click New field to create it. If you are searching, clear the search box.
Why can I not drag First Name or Last Name?
The real form always prints them side by side at the top, so there is nowhere else for them to go.
I changed a label, but the lead still shows the old name.
A label is only the wording on this form. The field keeps its own name on leads and in reports. To rename the field itself, use the Fields page under Settings.
How do I change the choices in a dropdown?
The choices belong to the field, not to the form. Click the field, then click Change them on the Fields page in the panel.
A workflow in a rule is greyed out.
It is the workflow chosen under Apply workflow on the Settings tab. It already starts for every lead, so it does not need a rule.
A rule on a Checkbox Group shows “Choose...” where the box should be.
The rule was made before the form builder and does not say which box it is about, so it never matches. Pick the box from the list and click Save field.
A rule shows “no longer a choice”.
The rule compares with a choice that has since been renamed or removed on the Fields page, so it can no longer match. Pick one of the current choices and save.
My trigger did not start its workflow.
Open the field and check three things: the switch is on, the rule matches what was actually entered (text is compared exactly, capital letters included), and the workflow in the rule is the one you expect. Then send a test submission through the form’s link.
The robot check does not show on my own website.
That happens when a designer has copied the form’s code onto your website. Add the website’s domain under External form domains on the Settings tab, and ask your designer to update the code from view the form source.
The redirect does not happen.
A redirect does not work for a form that is embedded in a frame. Link to the form instead of embedding it, or leave the redirect empty.
I removed a field by mistake.
Add it again from the Add a field list. Nothing was lost from your leads. You will need to set its label, its Required switch and any trigger rules again.
