How to get quantites added into multi selection widget?

I'm trying to accomplish something I can't figure out. With the PayPal and Stripe payment options, you can lump in pickable quantities of things with multiple quantities. The issue is it doesn't break that information out on the export of the form. So I'm trying to use a calculation wizard to calculate those fields by the size selected but I can't figure a way to get a quantity in there and then have it figure out the match.

While doing this is will give me each thing in its own line on the export. If you see the link attached for the form I am working on and scroll down to the Products & Payment section you can see what I am talking about. I would like to have the registrants pick a size and select a quantity if it's more than one. I just can figure it out.

Help, please!!!

Thank you,

Jan

I can't figure a way to get a quantity in there and then have it figure out the match. — I'm assuming that you already know how to pass the total to a payment field with user define payment as your payment type, right?

If you are not aware yet, you'll need to setup your payment option as shown in the guide I've shared above.

That should allow you to assign a value to each quantity and pass the total to your calculation field and that calculation field will pass the value to your user defined amount field.
