	   $command->bindParam(":Language_Name",	$language,		PDO::PARAM_STR);
	   $command->bindParam(":Active",			$active,		PDO::PARAM_STR);
	   $command->bindParam(":Disp_Order",	  	$displayOrder,	PDO::PARAM_INT);	 	   
	   $command->bindParam(":Action",			$action,		PDO::PARAM_INT);
 try {
		   $this->msg = '';	
	       $command->execute();
		} 
		catch(Exception $e)
	    {
			//$this->msg = substr($ex->getMessage(),0,-30);
			$this->msg = $e->getMessage();
//			$this->msg = substr($e->errorInfo[2],0,-30);
