    Your $message variable has local scope within the login function of the Users class, so you can't use it outside of that function as written currently. You could save it into your session, ie:

    $_SESSION['message'] = 'Wrong Combination';

    or better yet make it a member variable of the Users class:

    class Users {    
  protected message = '';

  public function getMessage(){ return $this->message; }

  function login($find='') {
    if(($rows["email"] == $email)&&($rows["password"] == $password)){
      $_SESSION['email'] = $email;
      $_SESSION['password'] = $password;
      if(isset($_POST['remember'])){
        setcookie("cookname", $_SESSION['email'], time()+60*60*24*100, "/");
        setcookie("cookpass", $_SESSION['password'], time()+60*60*24*100, "/");
      }

      $_SESSION['user_id'] = $user_id;
      return true;
    }else{
      $this->message =  'Wrong Combination';
      return false;
    }
  }
}

    Then inside the login form where you want to display the message:

    <?php 
  $message = $user->getMessage();
  if (!empty($message)) 
    echo $message;
?>

    By the way, I don't see where you are instantiating the Users class. I assume you are creating $user in code not shown from your use of it in login.php.
