    Stop Duplicate Field Values

    Asked by cavaliergrp on July 25, 2014 at 04:07 AM

    Good Day

     

    How can I use Jotform to stop the entry of duplicate entries for a specific field.

    Our form has a invoice number value, I only want the form to accept a unique invoice number. In other words if the invoice number was already captured the system should stop you.
