Google checkout in MarketPress Not working correctly

I am using google checkout as a gateway for payments. I have set the setting just as it told me to. The problem I am having is then member buy a product and then go to the checkout pages it ask for there shipping address information and below is a button to continue checkout. If you press that button it will let you confirm your information and then when you press the checkout button for the last time it take you to the order status page. It does not ask for payment information or take you to google checkout to enter payment information. Basically customer are getting free products.
