How to pass a calculation to a payment field

Hello,

I followed the instructions for the calculations, but was not clear if I have to do the calculations for each price if so how to I input each number. I have a person who register on the vendor form so is the payment there in paypal or do I need to have the client resubmit everything again? Please advise. I added the the calculation to also the sponsorship application as well.

vendor application

Then just copy/paste the options. And enable calculation values. Add the prices to the calculation values.

It should now work like this:

Next you have to pass your calculation field to your payment integration.
