You are looping over the array sequentially from 1 but are you sure your array key values are sequential from 1 as well?
Your loop goes 1, 2, 3, which means it will expect to find session.shoppingCart[1].itemid, session.shoppingCart[2].itemid and session.shoppingCart[3].itemid. But are you sure those are indeed the key values in the session array? If your array key values go 1,3,4 then that will definitely break things.
