How to check if an answer is unique?

Hi,

We are using jotform on a single iPad as a kiosk station to collect congregation contact info at our church. Is there a way to ensure that people only register once http://essaywriter.fun/? 

I'm thinking something along the lines of:https://trackeasy.fun/usps/

They enter their email first, and if it's already in the database a message pops up saying they have already submitted a form. And maybe give them the option of "cancelling" or "editing existing profile" https://showbox.tools/

Thanks

It is possible to check if a field user has entered already exist in the submissions.

To enable this option, you need to go to form Settings, select Show More Options, and enable Unique Question:

You will see a list of all questions in your form, and you need to choose the one you wish to check if it's duplicate.

Unfortunately, this will be tested after the submission has been made. You are able to show a premade message, which is not possible to modify with links.

Let us know if you have any additional questions.
