Pagination and routing

I've read several archived posts from Ellislab about pagination and I dont understand why its not working. URLs are my weakness and http in general.

Help!?

In routes.php I have (second line down)

PHP Code:

$route['log/delete_img/(:any)/(:any)/(:any)'] =     'logs/delete_image/$1/$2/$3';
$route['log/(:any)/page/(:any)'] =             'logs/log/$1';
$route['log/(:any)'] =                     'logs/log/$1';
$route['log/(:any)/(:any)/date'] =             'logs/change_date/$1/$2';
$route['log/(:any)/(:any)/text'] =             'logs/edit_entry/$1/$2';
$route['log/(:any)/edit/(:any)'] =             'logs/edit/$1/$2'; 


and

PHP Code:

    //'uri_segment'        => 3,
    'base_url'        => site_url() . '/log/' . $slug,
    'prefix'        => '/page/',
    'total_rows'        => $this->user_model->get_count_entries($plantid),
    'per_page'        => 2, 


controller

PHP Code:

    public function log($slug = NULL) {
        //method code here
    }
