Sorry it's very spralled out. I managed to get hold of some code to display a multi-dimensional array and I'm just dealing with the 'add products' bit at the moment. I can get the $GET data to be added to an empty cart but then when the page comes back again (ie to add data to the end of the existing cart) it has a problem (I don't think the array is being stored properly in the session variable 'cart'. I think I've just missed out a '&' somewhere but I'm not exactly sure where. Can you use $array[]=$var to add elements to a multi dimensional array?
The line "$newprod=array('1' => &$item);" is just to see whether I could manually add a second item to the array.
Thanks again,
Richard
