parse error problem—please any help

I know I’m missing a bracket or some piece of code is open… but my eyes can’t seem to find it. Any help would be greatly appreciated… I’ve been staring at the same code for too long. Here’s the HTML of my sidebar:

<div id="sidebar">
<div id="noindent">
<ul>
<?php /* If this is the frontpage */ if ( !is_home() ) { ?>
<li>
<h2><a href="https://www.chazsouthard.org">Home</a></h2>
</li>

<li>
<h2><?php _e('Author'); ?></h2>
<ul>
Chaz Southard, Boston, MA, naturalist, poet, designer, research advocate, amateur photographer, survivor and dreamer <a href="https://www.chazsouthard.org/wordpress/?p=54"&gt; {{Bio}} </a></ul>
</li>
<!--
<li>
<h2><?php _e('Search'); ?></h2>
<?php include (TEMPLATEPATH . '/searchform.php'); ?>
</li>
<?php if (function_exists('wp_theme_switcher')) { ?>
<li>
<h2><?php _e('Themes'); ?></h2>
<ul>
<li><?php wp_theme_switcher(); ?></li>
</ul>
</li>
<?php } ?>

<li>
<h2><?php _e('Categories'); ?></h2>
<ul>
<?php list_cats(0, '', 'name', 'asc', '', 1, 0, 1, 1, 1, 1, 0,'','','','','') ?>
</ul>
</li>

-->

<li>
<?php get_links_list(); ?>
</li>

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

<!--
<li>

<h2>Meta</h2>
<ul>
<?php wp_register(); ?>
<li><?php wp_loginout(); ?></li>
<?php wp_meta(); ?>
<li><a href="https://validator.w3.org/check/referer&quot; title="valid xhtml 1.1"><img src="images/validxhtml11.png" alt="valid xhtml 1.1" /></a></li>
<li><a href="https://jigsaw.w3.org/css-validator/check/referer&quot; title="valid css"><img src="images/validcss.png" alt="valid css" /></a></li>
</ul>

</li>
-->
</ul>
</div> <!-- end of noindent -->
</div>

<!--
<div id="sidebar2">
<div id="noindent2">
