To connect the Form Calculation widget with the PayPal Pro (or any other payment processing tool) on your jotform you would need to enter the payment tool wizard and select where to get the value from option under donations.
Now that is a quick explanation where to find it if you only needed to get reminded where it was, but if you need a bit more details on its location, we have a great guide for that here: How to pass a calculation to a payment field
Of course if you have any questions along the way, feel free to ask and we would be happy to answer them. :)
