IE Checkout page quantity number update broken

I am having a similar issue. The cart page actually says there is nothing in the cart when I add or remove items from the cart. I don’t get an error but this is in Chrome as well.

I tried to take a look at the WPEC github but whoa. haha so not sure if this problem has been identified already or not. I’ve identified that jquery error. I don’t know enough with that to fix though.
