liz is right... you are resending your data to the page, and the 
script pulls it out and adds another item...

i get around this a different way, however...

- i request the cart item from the form submit...
- i check for a session variable named 'foo', if it isn't there...
- i add item to the cart...
- i set a session variable named 'foo'...
- if, however, foo was already there, i just display the page...

how do you clear 'foo' to add more products?

simple, do that on your product selection page... kill 'foo' there, 
effectively forcing all cart submissions to come only from that 

does that make any sense?
