A shopping cart has a table called "cart" where the customer's selections are stored.
The customer buys 1 item of Product C, 2 items of Product H and 3 items of Product T.
I need to be able to count the number of PRODUCTS bought NOT the number of items. i.e. the answer here is 3.
What is the EASIEST way to do this?
Thanks.
