Unique Field Validation can be found in any form by opening that form and navigating to Advanced > Restrictions > Unique Field settings.
By designating a field on the form as a Unique Field, you can ensure that a single value can only be selected once. For example, if you designate an email field as the form’s Unique Field, and someone submits the form with happyllama@bahamallamas.net, no future submissions of that form can be made using that email address. At this time, only one field on the form can be designated as a Unique Field.
- Designate the field on the form that you want to be used as the Unique Field
- This is the error message that will display to any future submissions that duplicate previously submitted data in the Unique Field.
