Coffe Template doesn't support tabs in VM Product flypage

I searched these forums and haven't seen anything... The Tabs on the flypage (Product Details;
Ask a question about this product; and Customer Reviews) are not functioning as they do in the gk_mystore template... really, they don't function at all.

Cloud server, Joomla 1.5.23, Firefox browser (actually ANY browser)

Ideas???
