OK please ignore a lot of the above, I did some searching and have it "bascially working".
I still have these issues:
Where does "echo category_discount_display($current_category_id);" EXACTLY go in the Products section of index.php?
Right now the discount ONLY shows up on the Order Confirmation Page. How do you get it to show up in the shopping cart?
My discount setting is 22:2:7:p
I thought this meant a buyer would get a 7% discount on 2 or more items purchased from category 22. The discount shown is $14 (2 x $7). How does one give a PERCENTAGE discount?
Here is the website I am working on: https://www.rainbowbabe.com/catalog/index.php
Thanks in advance for any help you can provide.
