When a form does not use Form Logic, you can choose to make fields required, hidden or locked (read-only) - but whatever you pick will apply in the same way to every record that is created. In the "Client Intake" record example below, there is no way to tell the user that they must fill out school information only when the client is a child. Or, if the client is an adult, there is no way to tell the user to skip the school information, and instead fill out the employment information.
​

Form Logic allows you to add conditional rules to a form that apply in very specific cases. Fields can become hidden or un-hidden, required or not, locked or unlocked; use various look up lists depending on other field values; set a value based on other field options; or be highlighted based on what your users fill out.

What Happens to Data When Form Logic is Applied?

Form Logic does not, and will not, delete or change data that has been entered into a form.

What Form Logic can do is show or hide data. Form Logic can reveal data fields that are required to be filled in before you can save the form. Form Logic can change what your users see when they fill out a record. Form Logic can determine the options users see for a dropdown field. Form Logic can set a value based on another field's value. 

Form Logic is composed of rules. Each rule is composed of conditions and actions.
​ 

It can be helpful to think of each Form Logic rule as an "if/then" statement:

Condition: If [x] field has [y] answer,

Action: Then perform [z] action.

Conditions: describes what fields and what kinds of data or which answers entered into a form will set a Form Logic rule in motion. A rule can have more than one condition.

In practice, a Form Logic condition is built in similar fashion to a filter in a report.

Actions: describe what will happen after the condition is met. Actions can be applied to a specific field or to all of the fields in a section. A rule can have more than one action associated with it.

For a specific field, the choices for actions include:

- Require

- Unhide (make visible)

- Lock (make read-only)

- Highlight

- Use Look up List

- Set Value

For an entire section, the choices for actions include:

- Unhide

- Expand

- Scroll to

- Require All Fields Within

- Lock All Fields Within

1. Open the Administrator tab,

2. Select Form Designer, then Standard Forms in the left hand menu.

3. Select the form you would like to edit and under the Actions tab, select "Edit."

1. Open the green gear box at the top of the form.

2. Under "Settings," select "Enable Form Logic."

3. Click Apply and publish.

Because Form Logic can make fields and sections required or un-hidden, it is a good idea to find these fields in your form before you start adding Form Logic rules - and make sure they are already hidden or that they are not already required.

In many cases, it is easiest to add rules and actions to an entire section at once. This can be a quick way to add Form Logic to an existing form.

At the bottom of your form under the System Fields section, you will now see a section called "Form Rules."

1. Click "New Rule" to add a new Form Logic rule to your form.

2. Open the green gear box.

3. Edit the name.

4. "Show on Palette" means that the name of this rule will be visible to users as they are filling out your form. You can select to show it or hide it.

5. Click "Apply."

Forms cannot be published until all Form Logic rules have been configured. If you need to delete a rule:

1. Open the gear box to the right of the rule you would like to delete.

2. Select "Delete."

Note: Click on the rule name to expand it and see its current conditions and actions. Clicking the arrow to the left of the name will not expand the rule.

1. To add a new condition to your rule, select the "+" on the left hand side.

2. Select the field that will govern the actions to follow.

3. Select an operator, like Equals, Begins With, Contains, etc.

4. Add the answer.

5. Select Apply.

Form Logic rules can have more than one condition. This can be useful if answers in more than one field can meet the conditions. In the example above, users can mark a client as a "child" or the client can have an age at intake of less than 18 - either one of these answers can indicate the client is a minor or a child.

Once you have added more than one condition to the same rule, a section called "Condition Logic" will appear. You can indicate if both the conditions need to be met ("1 and 2") or if either of the conditions need to be met ("1 or 2").

To delete a condition,

1. Expand the rule by clicking its name.

2. Click the text of the condition you would like to delete. This will open the condition for editing.

3. Select Delete.

1. To add a new action to your rule, select the "+" on the left hand side.

2. Choose if your rule will apply to one field or to an entire section.

3. Select the action.

4. Indicate which field or section it will apply to.

5. Select Apply.

Form Logic rules can have more than one action. This can be useful if the same condition, when met, should to be applied to more than one field or section on the same form. In the example above, if a client is identified as a child, then the "Child Information" section must be unhidden (or visible) and the "Current Grade" field will be made required.

To delete an action:

1. Expand the rule by clicking on its name.

2. Click the text of the condition you would like to delete. This will open the action for editing.

3. Select Delete.

1. Using Form Logic with an append only field: actions can only be triggered by what is in the editable text box portion of the field. This field would work best with Form Logic rules based on "is empty" or "is not empty."

2. Using Form Logic with a multi-select field (like a multi-select drop-down or checkbox): Form Logic rules will not work when based on "equals;" for best results, use "begins with" or "contains."

3. To deactivate a field which has been used in a form rule, first delete all Form Logic conditions and actions that apply to the field.

4. Set Value has a limit of 80 characters, which is based on the number of characters there can be in a form logic action. All characters in a Set Value action after 80 will be truncated.

5. You cannot use a set value action for Masked Option, Likert Scale or Milestones/Goals fields.

6. Incomplete Form Logic Conditions or Actions WILL cause issues/errors on your form. Please ensure that all Conditions and Actions are filled out when using Form Logic.

7. Secure Fields cannot be used with Form Logic.
