Hi just wondering if anyone can help me. i am trying to get a shopping cart working and am having a few problems. on the webpage the user has 2 option to rent or buy. the problem that i am having is that if i click rent, it adds the rental and buy option to the shopping cart, the same thing happens if i click the buy button.
