        (!isset($_SESSION['homepage'])) { $_SESSION['message']==$_SESSION['message']}; // if message comes from anything other than the login post

        if (isset($_SESSION['loggedin'])) {$_SESSION['loggedin']=$_SESSION['loggedin'];} else {$_SESSION['loggedin=']='000';} 

        if (!isset($_SESSION['message'])) { $_SESSION['message']='Please Log into an Account';}

    } else { $_SESSION['loggedin=']='000'; $_SESSION['message']='Please Log into an Account'; }



if (isset($_POST['email'])) {
unset($_POST['email']);
unset($_POST['confirmemail']);
