Pageviews Plugin

Hi, i’m writing my own pageviews plugin, but i’ve got a problem. It all works, except one part, the part where it displays on the index page how many views there have been. I’m posting the code which is going wrong:

<?php
/*
Plugin Name: PPP (Pageviews Per Post)
Plugin URI: https://schot.xs4all.nl/index.php?p=4
Description: Pageview counter for posts, automatic. My site is online, when i'm online ;)
Version: .01b
Author: jmschot
Author URI: https://schot.xs4all.nl
*/
function views() {
$count_id = $_GET['p'];
if ($count_id == NULL) {
global $id;
$result = mysql_query("
select *
from wp_count
where count_id='".$id."'");
$r=mysql_fetch_array($result);
echo $r[count];
return;
}
... here follows the code where it displays the views at the post itself, like index.php?p=3, which does work ...

Does anybody see what i’m doing wrong?
