you're only returning the value, and not setting the global variable you could place a "global $handle_guess:" as the first line of your function or you could do "$handle_guess = get_handle($lastname, $firstname);"

So far the only way to make it work is echo get_handle($lastname, $firstname); which is not beautiful. BTW is there a limit to the length of a command. If I can't figure this out then I will have five or six of this "echo" statement concatanated together.
