How to have a unique formula on my formAsked by BradshawChristian on March 06, 2017 at 05:18 PM
I am creating a payment form and I want to do a unique formula setup for it. I'd like to have the following in my form:
Field 1 (typed in): An numerical amount typed in by the person completing the form.
Field 2 (Derived, not keyed in): A "surcharge" amount that is derived by multiplying Field 1 by 2.98%
Field 3 (Derived, not keyed in): A total that adds Field 1 and 2 together, used to be the amount charged to the payment processor.
Is this possible? If so, how could I do that?
