shopping cart

Back again...

 

Im having a little trouble with my shopping cart script ???. When adding an item to the cart, it retrieves and displays the size submitted from the form. However, the size for previous items added to the cart change to the size of the most recent item added to the cart. So items in the cart have the same sizes. Where am i going wrong
