    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
