Parent::controller

[eluser]suzie[/eluser]
Dear Sir,

Am watching the video tutorial from the site, but when am adding the function BLog:

<?php
class Blog extends CI_Controller {

function Blog()

{
parent::Controller();
}

function index()
{
}

}

?>

it gives me an error:

Fatal error: Call to undefined method CI_Controller::controller() in C:\wamp\www\application\controllers\blog.php on line 8



Any help please??
