Thanks Chris, Hotel table is indeed innodb, and items_no is int(16)....here is hotel table CREATE TABLE hotel ( items_no int(16) NOT NULL auto_increment, INDEX (items_no), PRIMARY KEY (items_no) )ENGINE=INNODB; I did read the comment with the same error 150, but I cant grasp pretty well whats wrong with this table. P:S Keep in mind that I am not very well experienced in database design.
