    }
    
    function index($pgoffset=''){

        $config['uri_segment'] = 3;
        $row    =      $this->Profile_model->get_selected($this->session->userdata('user_id'));
        $this->data['username'] = $row->username;
        $data['count_no'] = ($this->uri->segment(3)=='')? 0 : $this->uri->segment(3);
