How can the submitter's edit the form submission once submitted?

Hi there, thanks for your response but i am not able to get the link. Could you help me with getting the edit link.

what url needs to be added

I checked your form and I can see that the autoresponder email content already has {edit_link} on it. This is just a placeholder but the actual link will appear in the actual email.

I can verify this with the autoresponder email received by your most recent submitter, here's a screenshot:

Hope that helps. If you have any questions, let us know.
