Hi, I have installed the latest version of the google checkout contribution: http://www.oscommerce.com/community/contri...Google+Checkout in my site. But when clicking to the google checkout button from the front end it is taking me to the https://checkout.google.com with the following error: "Oops! Shop559 has sent Google a shopping cart with errors in it. We'll contact them to ask that they fix this problem. As this could be a temporary issue, you can go back in your browser to try checking out again." Can anybody help me out how this error can be resolved or what is causing the error. Thanks!
