Redirect for IE6 and below users RESOLVED

<?php
if (eregi("MSIE",getenv("HTTP_USER_AGENT")) ||
eregi("Internet Explorer",getenv("HTTP_USER_AGENT"))) {
Header("Location: http://twodayslate.com/ieindex.php");
exit;
}
?>I found this but this just redirects all IE users. IE7 users are fine.

Thanks.

I got an answer but I get an error
