Hey...
Ok Firs Mike.. Yes I have been "fixing" some of her scripts and saw she used this too.. Unbelievably I also so this point about the string in the string without concat op's but incredibly it works.. Now back to reason why it don't work.. Okay Jenny.. Hi again :) Next.. Do you have anything actually IN your table ({$config["prefix"]}_users) ?? If so does the username in it match {$session["uid"]} ?? If it doesn't and mysql_query returns a error cos a) table don't exist or b) some other sql error such as column name wrong etc.. Then mysql_fetch_array will cough up error.. This happened when I setup your scripts on my box.. And whenever I setup any scripts in which I don't yet have any records matching the query so mysql_fetch_array goes nuts.. Ok.. Hope it helped.. ::::::::::::::::::::::::::::::::::::::::::: : Julien Bonastre [The-Spectrum.org CEO] : A.K.A.

Why? Because the mysql_query failed, and so $ret was not assigned valid result resource. This is why you should ALWAYS check the return value of a mysql_query call before trying to fetch its results. > > Now, why is the query failing?
