Yes, it was solved before I replied. I just wanted to point out why it worked in the situations that it did and why it did not work in the situations that it did not. As the OP had been staring at it for too long, all of the code started to blur together. :) Anyway, it's a moot point now. I think the information you provided about the link identifier was solid advice... I was just trying to point out that using two different variables when specifying the link identifier in mysql functions was what gave him so much guff. // Todd -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
