Pagination link is not working properly as you can see in my website (bottom right)
http://www.donaldson.com.au/new/partdeta...ts/17953/1

Controller code:

class Partdetail extends CI_Controller {

function index()
{
$this -> load -> library("labels");
$labels['labels']= $this->labels->getlabels();
$this->load->model('partdetails_model');
$this->load->library('smarty_parser');
$this->load->helper('html');
$this->load->helper('url');
$this->load->helper('form');




$this->smarty_parser->parse("ci:partdetail_view.tpl", $data);

}

function eqivalentparts(){
$this->index();
$this->load->model('partdetails_model');
$current=$this->uri->segment(4);
$current2=$this->uri->segment(2);
$part_id=$this->uri->segment(3);

$config['full_tag_open'] = '<div>';
$config['full_tag_close'] = '</div>';
$config['per_page'] = '100';
$config['base_url'] = base_url().'partdetails/eqivalentpartsLst/'.$part_id.'/';
$config['total_rows']=200;
$this->pagination->initialize($config);
$ary_eqiuvalentparts=$this->partdetails_model->get_eqiuvalentparts($part_id,$config['per_page'],$this->uri->segment(4));

$data['result']=$this->partdetails_model->generate_equivalentpartView($ary_eqiuvalentparts);
$data['pagination']=$this->pagination->create_links();
$this->smarty_parser->parse("ci:partdetailview.tpl", $data);
}
}



Please any one help me to resolve the issue ASAP.
Thanks.

in eqivalentparts()

Code:

$config['uri_segment'] = 4;

It's in the user guide.
