Can't change quantity in cart 4.0.3
 

I've been making some code mods and discovered that I can't change the quanitity of an item in the cart. Now I don't know if it is something I did or is it a bug in xcart.

Can someone with 4.0.3 installed try to change an item's quantity in the cart for me?

The cart works fine. More than likely you have done some modification like moving the "Discount Coupon" form up into the shopping cart form. The end result is that you would have a form nesting problem.

Revert back to the original template for the cart and you should see that it works OK.
