    Hi Team,

    Is it possible to make a field unique for the whole submission.

    For example, i am trying to make a form with unique phone numbers. If not unique i like to make a new action like delete the old entry with same phone number and create the new entry.

    Is something like this possible in your tool?


    Thank You,

    Arun Prasath

    Hello Arun,

    Unfortunately, we do not have a feature that would check duplicates and override any existing entry based on the unique data (field) that you have chosen. All submissions are unique and will be recorded individually in the form.

    A workaround, maybe, would be to ask submitters to update their entry if they want to - using the edit link feature.

    I hope that helps.
