Help with planning a CI project

Code:

function pages($slug){
    $data['page_data'] = $this->MPages->getPageBySlug($slug);
    $data['title'] = $data['page']['title'];
    $data['main'] = 'public_page';
    $this->load->vars($data);
    $this->load->view('template');  
  }

the above function is looking for a single parameter.
Your url of http://www.site.com/index.php/page/about-us/location/ is passing about-us into that parameter. So your model is looking for the record that has about-us as the slug

EDIT: Actually, I'm incorrect in the above. Sorry.
Your default is working because it's calling the index function.
In order to get the above method to work, you would need a url of something like http://www.site.com/index.php/page/pages/location/. You would need to call the method, then pass in the parameter
