Sidebar Widget Problem

I get an error on my sidebar at http://thetechkid.com when I try to use sidebar widgets. I am using the default WP sidebar code, and I can’t get it to work. This is the code i am using for my sidebar:

<div id="sidebar">
		<?php if ( !function_exists('dynamic_sidebar')
		        || !dynamic_sidebar() ) : ?>
		<ul>

			<li>
				<?php include (TEMPLATEPATH . '/searchform.php'); ?>
			</li>

			<!-- Author information is disabled per default. Uncomment and fill in your details if you want to use it.
			<li><h2>Author</h2>
			<p>A little something about you, the author. Nothing lengthy, just an overview.</p>
			</li>
			-->

			<li>
			<?php /* If this is a 404 page */ if (is_404()) { ?>
			<?php /* If this is a category archive */ } elseif (is_category()) { ?>
			<p>You are currently browsing the archives for the <?php single_cat_title(''); ?> category.</p>

			<?php /* If this is a yearly archive */ } elseif (is_day()) { ?>
			<p>You are currently browsing the <a href="<?php bloginfo('home'); ?>/"><?php echo bloginfo('name'); ?></a> weblog archives
			for the day <?php the_time('l, F jS, Y'); ?>.</p>

			<?php /* If this is a monthly archive */ } elseif (is_month()) { ?>
			<p>You are currently browsing the <a href="<?php bloginfo('home'); ?>/"><?php echo bloginfo('name'); ?></a> weblog archives
			for <?php the_time('F, Y'); ?>.</p>

			<?php /* If this is a yearly archive */ } elseif (is_year()) { ?>
			<p>You are currently browsing the <a href="<?php bloginfo('home'); ?>/"><?php echo bloginfo('name'); ?></a> weblog archives
			for the year <?php the_time('Y'); ?>.</p>

			<?php /* If this is a monthly archive */ } elseif (is_search()) { ?>
			<p>You have searched the <a href="<?php echo bloginfo('home'); ?>/"><?php echo bloginfo('name'); ?></a> weblog archives
			for <strong>'<?php the_search_query(); ?>'</strong>. If you are unable to find anything in these search results, you can try one of these links.</p>

			<?php /* If this is a monthly archive */ } elseif (isset($_GET['paged']) && !empty($_GET['paged'])) { ?>
			<p>You are currently browsing the <a href="<?php echo bloginfo('home'); ?>/"><?php echo bloginfo('name'); ?></a> weblog archives.</p>

			<?php } ?>
			</li>

			<?php wp_list_pages('title_li=<h2>Pages</h2>' ); ?>

			<li><h2>Archives</h2>
				<ul>
				<?php wp_get_archives('type=monthly'); ?>
				</ul>
			</li>

			<?php wp_list_categories('show_count=1&title_li=<h2>Categories</h2>'); ?>

			<?php /* If this is the frontpage */ if ( is_home() || is_page() ) { ?>
				<?php wp_list_bookmarks(); ?>

				<li><h2>Meta</h2>
				<ul>
					<?php wp_register(); ?>
					<li><?php wp_loginout(); ?></li>
					<li><a href="http://validator.w3.org/check/referer" title="This page validates as XHTML 1.0 Transitional">Valid <abbr title="eXtensible HyperText Markup Language">XHTML</abbr></a></li>
