How may I resubmit changes to a previously submitted jot form?

If I am a user trying to submit changes to a previously submitted request using JotForm, how may use the same form, make changes and resubmit?  Thanks

If you have submitted a JotForm form that belongs to someone else, then you should have received the edit submission link, if you did not receive it, then you will need to contact the form's owner in order to get the edit link. 

If you have a form and want to allow your users to edit their submissions, then you may follow this guide: https://www.jotform.com/help/40-How-to-Let-Users-Update-Their-Form-Submissions-at-a-Later-Date 

You as form owner can edit the submissions as well, this guide will help you doing so: https://www.jotform.com/help/325-How-to-Edit-Submissions-Made-on-Your-Forms 

I hope this helps.
