good day everyone...

why is it that everytime i add this lines of code to my program, the grd_cart (my grid view for the shopping cart) does not appear? and the message for NO ITEMS IN SHOPPING CART appears when in fact, there are items in the database.

and one more thing, the shopping cart does not change items for each customer. i meant, when a customer logs-in, and selected items for his shopping cart and logs-out, the items that the previous customer added in his shopping cart is included to the next customer's shopping cart. please help me understand sessions in alpha five version 9.

God Bless!
