shopping cart submitting incorrectly
We created a shopping cart some time ago for this project and recently added two new products. It appears that some of the products (specifically Holiday Cupcakes and Babycakes) now are not submitting to the cart or are submitting but incorrectly to the order display page e.g. showing either the wrong product or just adding to an existing item. I have looked at the "add to cart" buttons and the data seems to be correct. Not sure what is happening???
I've attached the files.
