So I've been messing with facebook connect for about 10 hours now, and I still am not able to send a query using fql to Facebook and get back anything let alone keep my app from crashing. Basically, when I try to log in, it never calls the session:didLogin: function, where I'm trying to send my query from. And when I try to send it manually, the console says:

2010-01-19 22:44:49.821 Facebook[3396:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFDictionary setObject:forKey:]: attempt to insert nil value (key: session_key)'

PLEASE HELP ME!!!!!!!! I've provided my source files below.

Here's my header:

@interface FacebookViewController : UIViewController <FBSessionDelegate, FBRequestDelegate> {
FBSession *session;
}
//method called when I press button on screen
-(IBAction)Query;

@end
