eCart won't allow selecting a different product size and quantity on 'continue shopping'
I added a product to the cart (product, quantity and size), viewed the cart and then clicked 'continue shopping'. Tried selecting an additional size for the same product but it doesn't show up in the cart. Also, tried selecting both an additional quantity and size, but that doesn't show up either. I have to select an entirely new product to get anything to show up in the cart.
