When someone orders 2 different items everything goes crazy. Say they order 2 different items that each cost $8. In the cart it will show each item costing $16 (2*$8) but the subtotal will be just $16. It adds it up right in the cart but shows the price of each item as the subtotal. Then when you go to checkout, the only thing it calculates in the price is the first item you added. So if I added an $8 item, another $8 item and a $10 item the subtotal before shipping should be $26. It shows this in the cart (but also as the price of each item which is screwy) but when you go to checkout it only counts the first item ($8). It does, however, compute shipping correctly like it knows there are 3 items.
So it charges for the first item + the shipping cost on all 3 items but somehow skips the cost of any items beyond the first one,
This does not happen if I order 2 or 3 of the same item. Only if I order several different items.
I have attached what I think are the 2 problem files.
