Peter, thanks for your reply. I'm 100% unsure that register_globals is turned on. I've not tried any of your points as for some reason my code works and my errors have somehow disappeared. It simply doesn't make any sense. Although I did email my web host to see if register_globals were turned on and they may have done this, but I'm thinking its not that as nobody has got back to me. I printed out the contents of the $buy variable and it contained exactly what I expected it to so it seems to be behaving as it should, I'm just unsure as to why its working now - bizarre! Even when I passed the Catagory/Interests ID along with the product ID in the URL, that still produced errors but I wasn't going to stay up any later to try and solve it. All I know is last night is didn't work and now it does ! Thanks again for your reply.
