Now that you (hopefully) understand the problem, here's a solution for
THIS case:

<?php
if (!isset($content)) $content = 'about.htm';
switch($content){
case 'about.htm':
case 'story.htm':
include $content;
break;
default:
die("Page not found");
break;
}

You'll need to add one line for each page, but you will never accidentally
try to include a file you didn't mean to include.
