Maq Posted April 22, 2011 Share Posted April 22, 2011 Look at the MySQL UPDATE syntax: http://dev.mysql.com/doc/refman/5.0/en/update.html You're not specifying table names so your queries are failing.

BellQuestWars Posted April 23, 2011 Author Share Posted April 23, 2011 Nevermind, I got it to work... W3Schools had the wrong syntax ... Nightslyr's signature speaks the truth!
