Why is it not possible to edit selected products in a payment field?

Hi I received your kind response regarding how to edit SUBMITTED form entries and I should clarify what the actual problem is!

We have text fields which can be edited.  No problem.

We also have Tick Boxes linked to a payment value.  Which calculates the total to be paid via paypal.  In Edit mode I am unable to edit the submitted tick boxes.  There is no difference in the price paid, just some users have selected the incorrect sport they want to enter and pay for.

How can we adjust this?

Thanks

I have checked your form and noticed you are trying to edit the selections made on the "7. Please select the sports that you would like to play". Please note that this cannot be edited since it's a payment integration, changing the selections and submitting the form again would end up charging your user again. 

If you would like to change the selections, you would need to ask your user to submit the form again. 

I hope this helps.
