Even if it works the way you want it to, it's bad style. If I joined your project late and had to look at it I would not understand what you're trying to do. There's no reason for it, that's the reason isset() exists. if you want to check to see if a var is set, use: if(isset($var)) if you want to see if a var is set and non-zero, use if((isset($var))&&($var!=0)) - Mark
