Prevent duplication of Volunteer sign-ups

We’re using a form to get volunteers to automatically add their details into a table.

Is there a setting to make a Field have to return a unique value so that volunteers trying to add themselves again because they’re not part of the base and can’t see the list can’t re-add themselves?

Hey! I don’t think there’s a way to do this with Airtable Forms, but I’d recommend Typeform, which will allow you to add some additional logic, or even ensure that a user can only fill in a form once.
