Getting the URL to work

[eluser]ptechie[/eluser]
Hello all...

First of all, I am looking at Code Ignitor for the first time... so please excuse the novice questions and help if you can.

I've got a page under the base URL, treatments which works when clicked from the homepage.

I found this code, in app/controllers/index.php

function treatments()
{
$this->setPageTitle('Treatments');
$this->load->template('index/treatments.phtml', $this->data);
}

Now, there is a link on this page (treatments) that links to <base url>/cancer

I've got the cancer.phtml file stored in app/views/index/ (that is where the treatments.phtml is stored)

ISSUE: The page <base url>/cancer does not show up, I get a 404.

HELP!

Thanks
