I want to do something similar to this...
I've got 6 extra columns in my shopping cart for 3 groups of optional accessories.
So there are two columns for each accessory group, one for the accID and one for accPriceIncrement.
The discount that I want to apply is 50% off of any accessory (accPriceIncrement) that is in the cart, if someone enters a specific coupon code.
I have all of the code working for the coupon input, (I have several simple coupons setup that are working great).
I just don't understand how to make a discount that will take (50% off of accPriceIncrement) if (accPriceIncrement is not = NULL) and a coupon code is entered.
If this isn't clear, please let me know.
Thanks in advance!
