Fatal error: Call to a member function query() on a non-object in /home/mmoyles/public_html/halloffame.php on line 57


this is the line it is referring too


$q=$db->query("SELET u.*,g.* FROM users u LEFT JOIN gangs g ON g.gangID=u.gang WHERE u.user_level != 0 $myf ORDER BY level DESC,userid ASC LIMIT 2");



if you wish to see this go to www.zoneoftime.pcriot.com and register click on explore and hall of fame and it will come up
