How to prevent duplicate forms when using browsers back and forward button.

    A co-worker was registering a participant for an event. She hit the back button to correct something and when she went forward the previous registration duplicated. Is there a way to stop the duplication in case someone else completing the registration does the same thing?

    Hi,  if a user tries to edit or correct some information in the form by clicking the back and forward button of the browsers, that actually  will send another submission.

    I would recommend you to add an edit link in the thank you  message.


    1) Click on Setup & Embed

    2) Click on Thank You

    3) Click on Than You message

    3) Add this <a target="_blank" href=" VARIABLE  " >Here </a> and add the variable Edit link between quotation marks.

    This is ha it would look once the user submits the form: 
    Hope this helps, you can try my example here. If you need more help, please let us know.
