    Passing Total to Paypal - calculation fields, help quick please!

    Asked by kimkarlsonministries on August 14, 2014 at 11:47 AM

    Hi! I am selling registration for a conference and have set the form up to charge 349 before September 1 and 399 after September 1. I set up 2 separate calculation fields - 1 to calculate (product)(quantity) at 349, and the other to calculate (product)(quantity) at 399. Now I am trying to pass the calculations to my paypal payment field. I went to select "get amount from" but I have two fields to get the amount from (2 different calculation fields). How do I fix this? Is there a way to set a condition for which calculation field the payment wizard should take the custom amount from? Help, quick please!!

    Yes that's possible with "Update a form field value" condition.

    You still have to use 1 form calculation field and write two conditions for both 349 and 399 depending on the selected registration date. Make sure to use the same calculation field as the output like the following.


    If you need further clarifications about this, feel free to message us here.

    Hi, I did this and when I go to the paypal wizard and click "get amount from" it shows this:





    (It shows 4 'Calculation' in the drop down, and none of them take me to Paypal. I used the same output field as Calculation as far as I know.) Please help!

    Look's like you've managed to get it to work.

    Your form seems to be functioning according to what you want when I tested it here. I was redirect to Paypal when I submitted the form.

    Check this screencast.

    Let us know if there's anything you want me to check. Thanks!
