I cannot seem te reproduce the error with the same script, so I wouldn't
know. Are you very sure this is the EXACT script? no accidental switching of
backticks and quotes?


You do know however, that linebreaks are perfectly legal, and you dont have
concatenate your whole query?
So:
SELECT Venue.*,
CONCAT_WS(\' \', Users2.Firstname, Users2.Lastname,
Date_Format(Venue.Vnu_Add_Date, \'%b %e, %Y %T\' )) as Mnt_Add,
CONCAT_WS(\' \', Users.Firstname, Users.Lastname,
Date_Format(Venue.Lastmaint, \'%b %e, %Y %T\' )) as Mnt_Data
FROM `Venue`
LEFT JOIN Users as Users2 ON Venue.Vnu_Add_Userid = Users2.Id
LEFT JOIN Users ON Venue.Maint_Userid = Users.Id
WHERE Venue.Id = '.$Id_clean;

...works perfectly and will make your life a little easier.

Grtz,
