// filter for manipulating the element that wraps the content
echo apply_filters( 'nd_open_id_content', '<div id="content">' . "\n\n" );
// action hook for placing content above #post
nd_abovepost();
?>
<div id="post-0" class="post error404">
<div class="entry-content">
<p><?php _e( 'Apologies, but we were unable to find what you were looking for. Perhaps searching will help.', 'thematic' ) ?></p>

nd_belowcontainer();
// calling the standard sidebar
nd_sidebar();
// calling footer.php
get_footer();

Seems like there is no page id called 118.
For example your Contact Us page work fine with page id of208`.
Make sure you are passing correct page id.
