Can we install http://www.bbclone.de

this script?

I tried to catch the stats using the snippet

Code:
<?php
define('_BBC_PAGE_NAME', 'site');
define('_BBCLONE_DIR', 'bbclone/');
define('COUNTER', _BBCLONE_DIR . 'mark_page.php');
if (is_readable(COUNTER)) include_once(COUNTER);
?>
i added this code in header.tpl after in <head>

but it seems that
isn´t working, any ideas?
