Help with helpers

[eluser]gmask[/eluser]
Hi Met,
I tried what you suggested, but something's gone wrong. My helper:

Code:

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

function settings()
{
    // Get global settings
    $CI = & get_instance();
    $query = $CI->db->get('settings');
    
    if ($query->num_rows() > 0)
    {
        $row = $query->row_array();
        $settings['site_title'] = $row['title'];
        $settings['site_tagline'] = $row['tagline'];
        $settings['site_location'] = $row['location'];
        $settings['site_comments'] = $row['comments_enable'];
    }
    return $settings;
}

?>

My controller:

Code:

function index()
    {
        $settings = $this->snappy->settings();
        $this->load->view('index', $settings);
    }

But it returns this error:

A PHP Error was encountered
Severity: Notice
Message: Undefined property: Blog::$snappy

Fatal error: Call to a member function settings() on a non-object in ...\controllers\blog.php on line 22
