undefined variable in url with get parameter in codeigniter

First off, I fully intend to AJAXify my entire page, though I am first building each page as its own just for clarity's sake and to avoid some of the up front hassle involved in AJAX.

All was well until I received this error:

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: q
Filename: controllers/welcome.php
Line Number: 93

Here is my Welcome code:

    function find($cliqid = '')
    {
        $search = $this->input->get($q);
        $q      = $search['q'];
        if ($cliqid == '') { $cliq  = "Find a new Cliq to Join!"; } else { 
        $cliq                           = $this->logic_m->get_cliq($cliqid);
            }
        $data['page']                   = "Create a new cliq under the ".$cliq. " Cliq!";

        //build components
        $page['head']                   = $this->load->view('template/components/head', $data, TRUE);
        $page['header']                 = $this->components_m->header($cliqid);
        $page['cliqbar']                = $this->components_m->cliqbar($cliqid);
        $page['content']                = $q;
        $page['slideout']               = $this->components_m->slideout();

        $this->load->view('template/template' ,$page);
    }

and here is the URL thats opening the page /welcome/find/6/?q=234

$page['content'] is actually displaying variable $q correctly, so I am not sure why its throwing out an error, or how to get rid of it.

Thank you!

It's an issue with this line:

$search = $this->input->get($q);

It should be:

$q = $this->input->get('q');

$q isn't defined yet!

EDIT: You'll also want to take out the line below where $q is redefined.
