Royally messed up my navigation bars – eek!

As you can see here, my navigation bar is supposed to be a nice a simple bar across the top, with sub-navigation down the right side. All I was doing was adding in a little RSS feed link at the top, but deleted something by accident. I’m not exactly sure how I messed it up, or how to fix it: https://designhandemade.ca

Here’s the code that I futzed up:

<?php wp_head(); ?>
</head>
<body<?php if ( is_home() ) { ?> id="home"<?php } ?>>
<div id="page" class="clearfloat">

<div class="clearfloat">
<div id="branding" class="left">
<h1><a href="<?php echo get_option('home'); ?>/"><?php bloginfo('name'); ?></a></h1>
<div class="description"><?php bloginfo('description'); ?></div>

<div class="right"><?php include (TEMPLATEPATH . '/searchform.php'); ?></div>

<ul id="nav" class="clearfloat">
<li><a href="<?php echo get_option('home'); ?>/" class="on">Home</a></li>
<?php wp_list_pages('title_li='); ?>
</ul>

Any ideas? Thank you so so much in advance!
