    Why am I receiving multiple form submission?

    Asked by epitterson on January 13, 2017 at 10:06 PM

    I have a form that people can fill out and there are times when a person submits one form i receive multiple submissions via email as well as multiple submissions in the spreadsheet and I then have to go delete the duplicates.

     

    Any assistance with this would be great!

    Hi,

    Thank you for contacting us.

    I have checked your e-mail history and realized that you have got multiple notification e-mails. As you can see:

    This e-mails sent your e-mail address at the same minute but the seconds are different. I think the user's refreshed the "Thank you page". Maybe, the warning message was not shown cause of browser problem.

    I have sent test submission into your form and realized that just one notification e-mail sent. As you can see:

     

    Also, you can take advantage of our unique submission feature to block multiple submissions from one system of one IP address. Here is a guide to help you:  http://www.jotform.com/help/64-How-to-Set-Unique-Submissions-on-a-Form

    You can also use our unique question feature to prevent from submitting duplicate submissions. Example: You can set one of your forms question (like cell number or email address) to be a unique question. This will not allow a user to use the same cell number or email address to submit your form.

    Please let us know if you have any questions or issue.
