antubis

Hello, Will someone explain me how this extension works because I cant`t make it work on my osCommerce. I created an account, make a text link for product, open this link with another browser with a diffrent user, added it to cart, went to checkout and than paid using PayPal sandbox, the osCommerce said that the product is now pending. When I go to administration affiliate program I see no change. I guess I can`t get the exact idea for affiliate so .. can you u explain me how it works Thank you
