I have made a shop on one of the pages of my website with the paypal add to cart buttons. Some of the items I sell require a selection by the purchaser, for example T-shirt size. Is it possible to sync up the combo box with the Paypal purchase button, so that the purchaser's choice shows up in the paypal cart? How would I go about doing this, or what are my options so that he store functions in a user friendly way? Thanks so much for your help.
