Update Cart wont update

For some reason, buyers can't update product quantities from their shopping cart http://susse.com.au/store/

From a Product page they can Add To Cart any number of products, but from the Shopping Cart, it won't update to a different quantity of products.

The products appear to be listed ok. Here's the key settings for one product as an example:

Products Status: In Stock
Product Qty Minimum: 1
Product Qty Maximum: 0
Product Qty Units: 1
Product Qty Min/Unit Mix: Yes
Products Quantity: 10

Any suggestions would be great.

Thanks.

What happens if you switch to the Classic Template?

Does it work now?

Hi,

It was an omission in the template as you rightly suspected.

The problem was that the product id wasn't carried over when updating the cart quantity, that's why we were stuck with the original quantity we added to the cart. Our programmer found it and put the product ID in it's place in tpl_shopping_cart_default.php

Thanks very much
