error 1100

Hi people, I dont know why but am stuck trying to debug this problem. I keep getting error number 1100 (Table 'jobs' was not locked with LOCK TABLES) from PHP when i try querying a mysql database. It has me stumped because I am using the LOCK TABLES statement when locking the tables...but maybe there is something wrong with my code that i cant see... Here is the function i use to lock/unlock the table(s). I call this function before querying the database. $dblink is the MySQL Link Resource, $table is the table to lock, $grant describes how it should be locked (READ/WRITE), if $table or $grant are null then it assumes the tables are to be unlocked: function lock($dblink,$table,$grant){ //function to lock/unlock tables if(($table == null) or ($grant == null)){ $unlock = @mysql_query("UNLOCK TABLES",$dblink); return $unlock; } else{ $lock = @mysql_query("LOCK TABLES " . $table . " " . $grant,$dblink); return $lock; } } Any ideas? Thanks heaps :)
