Wish List not Working for Products Block


I’m really liking this cart but have run into this issue: the Add to Wishlist links do not work for products I’ve setup as “cross sells” in a manual products block on my product details page. You can see it in action here: [url]wildchildclothes.com

I’ve looked at the markup and it looks like its got all the necessary info there. Is there some reason why this just won’t work?

If anyone can offer any insight I would be grateful.
