How to have Unique Question Submission in JotForm

 Under Preferences > Form Limits > Unique Question: What does this functionality intend to do?

Please review also the user guide about limiting submission base on Unique Question on the form.

According to the description on the Unique Question option...

"Do not allow previously entered values."

What it does is, it allows having only a unique answer (no the same answer) on a specific question/field on the form.

Example, if you want to prevent having duplicated email address info from the end-users, you will set the E-mail field as the Unique Question.

This should result into having no similar email address data from the entire submissions the form will have.

Let us know if you need further assistance.

 

Makes sense. Thanks Jonathan.
