Hi Jason,

You are missing the ON clause. How are the Conference and Rooms tables joined??
i.e.

SELECT Conference.ConfNum, Conference.ConfName, Conference.CheckInBegin, ;
Conference.CheckInEnd, Conference.CheckOutBegin, Conference.CheckOutEnd, ;
Rooms.HallName FROM Conference INNER JOIN Rooms ;

ON Conference.Key = Rooms.Key ;

WHERE ;
Rooms.HallName=="Hewett" .OR. Rooms.HallName=="Manchester" INTO CURSOR tmp

HTH,
