How can I edit a submission that has a payment option without having to resubmit the payment?

I have a payment option on my form. Some people submitted their form with missing information. Now to go in and edit it, I would have to make another payment to submit to form again. Is there anyway around that?

You can ask users to edit their submission through the edit link.

Note that edit won't charge users a new. The payment field is disabled on edit link.

You can also edit the information to your end.

Or, why not make the fields as required so users cannot skip fields?
