    Is there a way to keep people from filling out the form twice?

    Asked by vanestes on June 16, 2014 at 04:28 PM

    We are wanting to use the form for voting purposes on our website, but we don't want people voting more than once. Is there a way to track email or something to keep them from being able to submit the form multiple times?

    Yes there is.

    To change this:

    1. Go to the "Setup and embed" tab while editing your form.

    2. Click "Preferences"

    3. Click "Form Limits"

    4. Change "Unique Submission" from "No Check" to "Strict"

    This should allow for only one submission to come from each IP address.  If there is anything else we can help you with please let us know and we will be happy to assist you.

    Thank you for using Jotform!
