How to avoid duplicate submissions?

Hello, may I know why we keep getting duplicate and even triplicates of submissions? This affects accuracy. We confirm that respondents made only one

Hey there!

Happy to help you today.

I would like to inform you that, to avoid duplicate submissions.

You can follow these solutions.

1. Setting unique submissions: You can make the form check the cookies and/or IP of a user before submitting the form. This will prevent the form to be submitted more than once if a cookie is already set or if the IP had already submitted the form. Please see how you can do it on this guide(this is where you are coming from actually, but I just wanted to point this out again):

2. Setting form limits based on a unique question: You can set one of your fields to be unique in your submissions. This means when a same entry is filled on that specific field the form prevents itself from being submitted. Please see how you can configure this:

3. Please try adding a Captcha field to your form to avoid duplicate submissions. Here's a guide that you can follow: https://www.jotform.com/help/205-How-to-Add-a-Captcha-Field

These options should resolve your issue. 

Do let us know if it helps.

Thanks.

Hi,

The duplicate submissions problem is now resolved. We added some preventive measures to help deter unwanted resubmissions of the previous entry. This should not happen again.

Thanks!
