To Dan....no problem...I often learn from multiple inputs....
To Ray....your suggestion to delete the shipping script from the cart page worked, as well as changing the line on the confirm page per your reply above.
The problem that I was seeing was upon returning to the cart after making it to the confirm page, the cart gave misleading and incorrect shipping numbers, but if I proceeded to the confirm page again, the shipping quote based on cart contents corrected itself and seemed right.
Thanks!
