edit user's submission

I'm still really confused..... I recently added a new field to my registration form and I now need to have users update their already submitted forms without creating duplicates. How do I do this?

Unfortunately, the edit link created in the email is attached specifically to each unique submissions of your form respondents.

You may need to edit their submission in your submission page.
