Get page content (comments form)

Hi there fellow wp-lovers.

I cant to get the content(comments and comment form) from this page: http://salong96.se/recentioner/ into the popupbox on: http://salong96.se/

Without success I have tried using:
<?php
$id = 124;
$p = get_page($id);
echo apply_filters(‘the_post’, $p->post_content);
?>
