    Payment module not passing custom input to calculation field.

    Asked by DrivePayments on June 26, 2016 at 09:07 PM



    We are using PayPal for out payments system and I'm trying to get our "CalculationAmt" to grab the amount the user inputs (so we can pass "CalculationAmt" to Salesforce) but it's not calculating the data when I select. Thoughts?

    Thank you

    Unfortunately it is not possible to pass the custom amount from the payment field into the "CalculationAmt"calculation field. The only workaround I can suggest would be to ask the user to input the custom amount in a textbox after they enter a custom amount in the payment field.

    Here's a demo form so you can see it in action: www.jotform.com/form/61778646081970 

    Select either "one time donation" or "monthly donation" to show the "enter custom amount" number field. When you input the amount, the "CalculationAmt" should update accordingly. You can also clone the form to your account and use it if you wish. Regards.
