    Is there a way I can allow an individual to submit a form only once?

    Asked by philaiellomarketing on January 03, 2012 at 05:34 PM

    I am using jotform to send a Thank You survey for my work clients and will give a discount to their next purchase. Each client who takes this survey will be given a Unique ID, and I will keep track of the purchases that way. I only want my client to take the form once however, is that possible?

    Currently, there's no surefire way to accomplish this with our form builder. Nevertheless, there are two methods at your disposal: Strict Check and Loose Check. Please see our user guide for details.
