Can end user revise submission without starting over?

Hello Bobjap,

If I understand your question correctly, you want to allow your users to edit their own submission data. Is that correct?

Yes it is possible to achieve your requirement by taking advantage of our "Edit Link" feature. Please take a look at the following guide which should help you:  https://www.jotform.com/help/40-How-to-Let-Users-Update-Their-Form-Submissions-at-a-Later-Date

Hope this helps.

Do get back to us if you have any questions.
