[Idiot Mistake] Need Help

Ok, So I am using a $_GET function as a main navigation tool. Yes, I am using PHP, I did not come here to get ridiculed, I came here for assistance.

So I have the script something like:

<?php
$page = $_GET['p'];

if ($page == ""){
require 'index.htm';
};

if ($page == "about"){
require 'aboutme.htm';
};

if ($page == "links"){
require 'links.htm';
};
?>

And I have seen this work before, However I am running this off a different server on my own IP address instead of on a host. Basically the error I keep getting is that "p" is not defined. So, simply "page.php" will not load, however "page.php?p" will load. I have never had this happen before. Usually if the $_GET is set to '', then running page.php by itself will just cause the index page to show up instead.

I really don't understand what I did wrong. Please help /prog/.

I'm sorry we could not conform strictly to your memetic standards.  Perhaps you would be more comfortable on one of 4chan's many friendly and predictable imageboards.
