VM Shopping Cart Module Doesn't show product list in the cart

[sephor]

I'm having a problem with this module, even checking "Yes" on the relative option in the backend of the moudle, nothing happens. Instead there's no problem with showing price.
What coul It be? A JavaScript conflict ?

Please Help Me , It's driving me mad 

Thanks
