    Not allowing duplicate email addresses

    Asked by kbebuilding on April 27, 2017 at 10:47 AM

    Hi there.

    I see that I can setup conditions based on one field equaling another, and I can even have form elements disabled if one email address contains the same address as another.  However you do not allow me to disable the submit button if the email address fields are the same.  The submit button is grayed out in the list of items I can disable based on the duplicate.

    What I'm looking to accomplish is not allowing any of the three email addresses on a form to be a duplicate of one of the others, and not allowing the form to be submitted if they are.  How can I accomplish this with Jotform?

    Thanks

    Rather than disabling the field, you can use a show/hide condition to hide it:
