AbleCommerce Shopping Cart Software

We have changed the layout of CategoryGrid3 to more easily add multiple items to the shopping cart at one time, as this really lends itself to some of our categories. However, we would like to have an Add to Cart button at both the top and bottom of the list. For our test page (at http://www.brewhaus.com/test-C173.aspx) we have put it at the top. We can add a second button at the bottom, but it is non-functional- when you click it you are taken to the basket, but the items are not added. Can anyone help on this?

Hmmm... we seem to still be having a problem with the sorting options with this category grid (just a modified version of CategoryGrid3, which does not work out of the box). If anyone has any ideas of getting the sorting to show the items in the order in which we have placed them in the Admin section, please advise.
