You need to either have a return statement in this function that says "return $var;" or you need to use the & sign, which lets you change the value of a variable outside the namespace of the function. Or scope. I forget which it is. Try your above code -- it shouldn't work. Erik ---- Erik Price Web Developer Temp Media Lab, H.H.
