I'd like to revisit this one last time. Below is the revised code I'm using, but I don't like having individual 'Add To Cart' buttons for each item. I've tried to find a way to have only one that resides outside the nested tables for all items, but without luck. It would need to send every item that has a quantity to the cart, but only those items. The URL that would be passed needs to look like this:

/shop.cgi? c=viewcart.htm&itemid=P74S&i_P74S=80&S2448S&i_S2448S=100&AC&i_AC=26

(The above URL is sending 3 items and quantities to the cart; 80 - P74S, 100 - S2448S and 26 - AC.)

Thanks again for all your help. I'm learning a lot on this list - albeit slowly! ;)
