How to stop form from being submitted twice?Asked by Dennis on February 23, 2015 at 08:35 AM
This is a registration form, to which app. 300 complete.
People who fill out the form get anxious and when they don't here back soon enough - they fill out the form again.
This wastes a lot of time going through the forms and eventually finding out there are 2 of them.
May I know which form you would like to apply that effect? You can actually do that by using the Form Limit option under Preferences. Here's the guide that you can follow: http://www.jotform.com/help/223-How-to-set-Form-Limits-Based-on-a-Unique-Question. Just choose a unique question or field so no repeating answer or value will be submitted, let's say you choose the email field, if email@example.com is already submitted, it won't allow for another one with the same value.
I hope that helps.
You're welcome, I'm glad that it helps.
