Once it has the proper permissions, the facebook session access token needs to be stored in the facebook_session variable so it can be passed in the Sharing() function. ActivityRestaurantDetails Our servers send over an array of offers. The offers need to be displayed on this page, the offer layout currently shown but the data needs hooked up and it needs to be able to show multiple, not just one offer.
