Array helpp .. urgent

[eluser]phpfresher[/eluser]
THIs is my controller:

function client_requirement(){
$miid = $this->userprofile->get_module_id('client_requirement');
$this->session->set_userdata('moid',$miid);
$this->login_page();
if(($this->userprofile->check_mod_permission($this->session->userdata('uid'),$miid,'add'))==false){
die("Access Denied");
}
if(($this->session->userdata('login_ok'))){
$data['client_requirement'] = $this->clientprofile->get_client_requirement();
$data = user_model_permission();
//$this->load->view('client_requirement/header',(user_model_permission()));
//$this->load->view('client_requirement/menu');
//$this->load->view('client_requirement/home',$data);
//$this->load->view('client_requirement/sidebar');
$this->load->view('client_requirement/main',$data);

}
}

Whats wrong with the above code ...it does not print the $client_requirement value..in the view section but does have value in controller section
