How can I choose which calculation transfers to the payment?

My form has two different calculation widgets so that I can have a coupon code discount. I had it worked out before I integrated payment, but now that I have added our PayPal-- I can't seem to choose which calculation is used for the payment total. I have tried altering which calculation is listed first and that does not seem to matter.

Please help!

In the payment field setting there is an option to choose which field to get the total from:

The calculation field is set from there.

Yeah--- I did that. There are two calculations. It is not choosing the correct one. How do I make it choose the correct calculation?

 Nevermind-- I found a work around.
