Hey, Thanks for replying, I tried using the test example of Petar Nedyalkov, but when i try to create the following: CREATE TABLE `profile_log` ( `profile_id` int(10) default NULL, `user_id` int(10) default NULL, `last_login` timestamp NOT NULL ) ENGINE=MyISAM CHARSET=utf8 I get an error on both ENGINE=MyISAM and CHARSET=utf8 What are they for really? can I omit them? or will that effect the program later on?
