MySQL Statement Failing in PHP

I am running a query in a php page that is coming back with no results. When I run the same query in MySQL Console, it gives the results. Any thoughts? mysql_select_db($database_Fund, $Fund); $query_rsRegisteredClasses = sprintf("SELECT tlogin.FirstName, tlogin.LastName, tcourse.Name, tschedule.Date, tschedule.StartTime, tschedule.EndTime, tlogin.LoginName FROM ((tregistration INNER JOIN tschedule ON tregistration.ScheduleUID = tschedule.ScheduleUID) INNER JOIN tlogin ON tregistration.StudentUID = tlogin.LoginUID) INNER JOIN tcourse ON tschedule.CourseUID = tcourse.ClassID WHERE tlogin.LoginName = '%s'", $user_rsRegisteredClasses); $rsRegisteredClasses = mysql_query($query_rsRegisteredClasses, $Fund) or die(mysql_error()); $row_rsRegisteredClasses = mysql_fetch_assoc($rsRegisteredClasses); $totalRows_rsRegisteredClasses = mysql_num_rows($rsRegisteredClasses);
