    How can I verify a value entered in text file to defined list?

    Asked by Martyn Thomas on December 13, 2013 at 09:14 AM

    I have a list of people who are allowed to fill in a form. Because the form will be public availble I want to beable to verify the e-mail address the user enters against a list of authorised e-mail addresses to prevent non-approced people from filling in the form.

    Is this possible?

    There is a special feature on jotform that can allow this. What you can do is to place the full form source code on your web page and then hire a web programmer to implement integration with your email database.
