    Custom Calculations to Paypal integration

    Asked by dorsetholidaylets on May 15, 2014 at 08:45 PM

    Hi this is a great step in the right direction, the only small point is it would be better to be able to use the result from the calculation in the Paypal amount. It appears that you have to caculate the amount first and show this and then show the amount again in the PayPal field to submit to PayPal. 

    It would also be great to be able to add posateg costs in the same way as you can for sellig products.

     

    Best regards David.

    Hi David,

    Currently, you can only do the custom calculations if you use the Calculation widget.

    So, it is really necessary to use it.

    The Paypal Custom Payment integration do NOT have any built-in calculation function, so you cannot use it to do the calculations.

    To be more effective, you can also just hide the Calculation field result like this 

     

    If you test my Custom Paypal Calculation form here http://www.jotform.me/form/41276627819464

    you will noticed that as if the Paypal custom amount itself is the one calculating the amount.

     

    Hope this help. Inform us if you need further assistance.

    Thanks!
