WordPress MU

So I'm using this code on my company intranet, and I got it mostly right, except everything after the last PHP code doesn't load. So something is causing a choke in my syntax, but I can't figure it out. Any help is greatly appreciated!

<?php // GETS THE LATEST FEATURE ARTICLE FIRST
$my_query = new WP_Query('category_name=Featured&showposts=1'); while ($my_query->have_posts()) : $my_query->the_post();
$do_not_duplicate = $post->ID;

// CHECKS TO SEE IF THERE'S AN IMAGE FOR THIS POST
$featured_pic = get_post_meta($post->ID, 'Featured Pic', $single = true);

// CHECKS TO SEE IF THERE'S A SET ALT TEXT FOR THIS IMAGE
$featured_pic_description = get_post_meta($post->ID, 'Featured Pic Excerpt', $single = true); ?>

<div id="featuredpost">

A bunch of featured post code				

</div><!-- featuredpost -->

<?php endwhile; ?>

<div id="non-featured-container">

<h2 id="non-featured-banner">Latest Articles</h2>

<?php // THE SECOND LOOP SHOWING THE ARTICLES AFTER THE FEATURE

if (have_posts()) : $i = 1; while (have_posts()) : the_post(); if( $post->ID == $do_not_duplicate ) continue; update_post_caches($posts);

// CHECKS TO SEE IF THERE'S AN IMAGE FOR THIS POST
$thumb = get_post_meta($post->ID, 'Thumbnail', $single = true); ?>

<?php include (TEMPLATEPATH . '/latest-site-news.php'); ?>
<?php if($all_posts = ah_recent_posts_mu_mod(WPMU_RSS_LIMIT, WPMU_RSS_CACHETIME)) : ?>
<?php foreach($all_posts as $all_post): ?>

<?php // for controlling the layout of the home pages bottom excerpts up to 10 posts
if($i == '1' || $i == '3' || $i == '5' || $i == '7' || $i == '9' || $i == '11' || $i == '13') { ?>

<div class="post-container">

<?php } // endif ?>
								<div class="<?php if($i % 2 == 0) { echo 'post-right'; } else { echo 'post-left';} ?>">

<div id="post-<?php the_ID(); ?>" class="post">
								<h2><a>guid ?>"><?php echo htmlspecialchars($all_post->post_title) ?></a></h2>

<div class="entry">

<?php echo $all_post->post_summary ?>

</div><!-- entry -->

</div><!-- post -->

</div><!-- post (left or right) -->

<?php // for controlling the layout of the home pages bottom excerpts up to 10 posts

if($i == '2' || $i == '4' || $i == '6' || $i == '8' || $i == '10' || $i == '12' || $i == '14') { ?>

</div><!-- post-container -->

<?php } // endif ?>

<?php $i++; ?>

<?php endforeach; endif; ?>

<?php endwhile; endif; ?>

</div><!-- non-featured-container -->
