    How to pass a calculation to a payment field ?

    Asked by amyfoundationweb on November 02, 2015 at 09:57 AM

    I have followed all instructions on http://www.jotform.com/help/275-How-to-pass-a-calculation-to-a-payment-field to pass a calculation to the payment field on paypal.

    But my paypal widget looks different, instead of 'Get Amount Field' I see 'Suggested amount' (Attached screenshot),

    How do I pick the field to take the calculation from on paypal widget?

    (My calculation field has already been setup in form)

     

    Thank you

    Hello , 

    I've cloned your form and I found the origin for your issue , well we are going to do it in a simple way,please follow the steps below : 

    1. First, rename the field from Donation Amount to Calculated Donation Amount and set it as a hidden field : 

    2. Now, add the form calculation widget and configure it as the image below, to pass a value from a field to a payment field, it should be a calculation field

    And rename it from "Calculation" to "Donation Amount" : 

    3. Now, you will be able to select the field "Donation Amount" :
