    How to prevent duplicated submissions

    Asked by RogerYelvington01 on February 10, 2015 at 02:46 PM

    How do I prevent multiple submissions from the same computer?

    My employees submit the form:


    And sometimes they will hit the submit button multiple times, and will create duplicate submissions.  How do I avoid this?  Thank you!

    I do not think that we have a mechanism to block the duplicated data. However, we disable the form Submission button once it is pressed.

    Since you use a custom code to validate and submit your form, can you try to disable the form submit button once it is clicked once?

    I have also submitted a ticket to our Development Team to see if we can add functionality to disable the duplicated submissions at some point.

    Thank you.
