You haven't given enough code to diagnose your problems, but assuming that you've followed the open graph instructions on the Facebook Developers site - http://developers.facebook.com/docs/opengraph/ - It would be a good idea pass your target URL through the Facebook Debugger (formerly the URL Linter) it will help show you any errors you have regarding your open graph tagging implementation:
