Thanks for the ternary expression explanation.
From the Product Options with eCart tutorial...
Does the shopping cart have to be recreated anytime the eCart object is changed?
I am confused by the Unique checkbox in eCart Columns setup. Can you help explain it.
Can you help me further with the calculations to add PayPal fees. Only some of our items will have PayPal fees applied, how would you suggest I handle that?
The PayPal fee for our use is 2.9% + $0.30 per transaction on US purchases and 3.9% + $0.30 per transaction on Outside US purchases. How would I enter these calculations and distinquish US versus Non-US?
