    How to pass calculation to a payment

    Asked by imagedsgn1 on May 28, 2015 at 12:06 AM
    2.  Is there a way to add check list with prices price options before payment, earlier on the form. Lets say I select option A earlier on the form which costs $20.  It will automatically add to checkout payment form and make the total $20

    You can to that by adding e.g radio buttons to your form and then set Calculation values for radio buttons options. 

    Then you need to add calculation widget to your form.

    Then you can pass a calculation to a payment field. Inside of this article you can find out how to pass a calculation to a payment field:
