[PHP] Function / String Problem

[Karl J. Stubsjoen]

Okay, what is wrong with this:

       echo "<br><br>...are you logged in: $LoggedIn()<br><br>";
// outputs:    ...are you logged in: ()

Function is:
function LoggedIn(){
  global $HTTP_POST_VARS
        if ($HTTP_POST_VARS["Login"] == "PHPIsCool")
        {return "YES";}
        else
        {return "NO";}
}
