Blank page?

[eluser]whygod[/eluser]
Why these codes below is not displaying anything?

Code:

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Admin extends MX_Controller
{
public $data;

    function __construct ()
    {
        parent::__construct();
        
  $this->data['message'] = '';
  $this->data['title'] = 'AdminS9 Control Panel';
  
        $this->load->model('users_model');
    }

    function index(){
  $this->data['password_header'] = $this->load->view('password_header', $this->data, TRUE);
  $this->load->view('password', $this->data);  

    }

}

I think there is an error causing this.
So what's causing this problem?

Thanks in advance.
