Oy!
Do you realize that you've got jQuery loading THREE times, each with different versions, on your site?
You'll want to clean that up if you intend to improve site performance.
While that's unlikely to be a direct cause of attributes not showing in the cart, it's still worth fixing.
You've definitely got custom code causing your problems.
The following HTML from your shopping cart page, including the misspelling, does not come built-in with Zen Cart:
<!-- To Display Attribute in Shooping Cart -->
<div id="attpingu">
</div>
Perhaps you should go back to whomever you purchased your template from and ask them to fix their bug?
