Some Products Will Not Add to Cart

I have search for the answer to this and cannot seem to find it.

I have recently taken over a site that was created with zen cart. I received several emails stating that certain products could not be added to the cart. The rest of the products work fine and add to the cart.

Does anyone know what the problem might be?

If you would like to see what I am talking about go to this page.

When any of these products are added to the cart it will show up as 1x and then blank. The name or the price does not show up.

Every other page works fine but this one.

worked fine for me, except shopper not taken directly to cart or given a indication it was added.

It does work if you go to the actual product page and add the items. But it does not work if you try to add the products from the page listed above. That page is where most customers try to add the items from and when we get the message with their order it just shows up as 1x (BLANK). So then we have to call the customer to see what they were actually wanting.

Any help would greatly be appreciated.
