passing url variable

[eluser]jmcc1982[/eluser]
This is how I reference the link:

<a href="&lt;?php site_url('special_deals/form');?&gt;?d=1" class="roll">

This is my Controller:

&lt;?php

class Special_deals extends Controller
{

var $data = array();

function Special_deals()
{
parent::Controller();
$this->data['current_menu_tab'] = "special_deals";
$this->data['message'] = '';
}

function index()
{

}

function page($page)
{
$this->load->view('special_deals/'.$page);
}

function form()
{
$this->load->view('special_deals/form');
}

}

/* Location: ./system/application/controllers/welcome.php */
