Credit Card Payment

I Have a working form in Wix to allow online registration to our shooting club's annual 3 day match. All is working well. By selecting family, donations, etc., I have a form field that has a total payment due. I need to be able to send this amount, name, email, and telephone number to the back end for processing.

I already have a pay now button that seems to work, but of course there is no name , email, or tele plugged in.

I have all the info to pass just don't know how. I have lots of code included in the forms, and other pages, but this one task eludes me. I have looked at so many YouTube videos, and Wix help screens and am going crazy. BTW, the item name/product name is the only constant CC field, i.e., "2024 Match Fee". I have so many variations of code commented out that I believe a fresh start is needed.

FYI, my info fields are named frmFName, frmLName, frmTele, frmEmail, and frmToPayment .

Me, our club, and MY SANITY appreciate your help.
