$q=$db->Fetch("SELECT name,level,money,points from users where userid=$userid");

 

The above is were it errors. I cant seem to find out why it is erroring. The only thing i can think of is because it is in a function. Just unable to think of a fix for it.

You need to either move this line...

 

global $db,$ip,$userid,$upassword,$uuser;

 

into yuor Theme function, or better still, pass these variables into it as arguments.
