Create custom logic for comparing and validating field values.
Many RevTrak Forms fields come with default validation rules. For example, an email field will validate that its input is a valid email on submission.
You can create additional custom rules to implement other validation checks. For example, you may want to make sure that the user enters different values in two different fields.
Custom validation rules can be added to any field or button, and they will be run when the step is submitted. If the rule evaluates true, the custom validation message will appear on the element you added the rule to. Step submission and navigation will not occur until the validation error is resolved.
For more complex rules involving multiple possibilities, you can combine multiple comparisons using AND and OR combinators.
