Before you read the bottom paragraph about further edits...is it possible just to do all of this through the new PS3 conditional options? I have one set up on this page Products_Detail.php?ProductID=2. Can I have it ad $2 if they choose the "Personlize" option?
I've attached a jpg with the column names and the unique attribute checked. If you add more than one book however, it still only shows up as one row above the first book. Just to make sure, I want to have it show up per book if I can.
