The seller does not accept payment

Hello,

Go to the site: nuovincontri.com  After Go menu: Altro (More) and then choose Negozio (Store). After, for example, charge scarico del film Il professore (download of the film The professor). After press Aggiungi al carrello>(Add to Cart.) It will pop-up that says: <nuovincontri.com>The seller does not accept payment. But it is not true. In Administrator payments are accepted. 

Please tell me something.
  
Thanks

each seller has to set up their own paypal section (when user is on their account page, there is a link for payments where avatar, connections, subscriptions, unregister, etc are).

Many thanks
