Where, oh where is my comments link?

OK, I’m completely stumped, and I’ve tried some of the information posted on how to repair this, with absolutely no results.

I’m using WP 2.0.

I have my pop-up comments links written into my post headers:

<?php get_header(); ?>
<div id="content" class="narrowcolumn">
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<div class="post">
<div class="posthead">
<h2 id="post-<?php the_ID(); ?>"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>
<p class="postmetadata"><?php edit_post_link('Edit','','|'); ?>
Posted on <span id="postdate"><?php the_time('F jS, Y') ?></span> | <?php comments_popup_link('No Comments »','1 Comment »','% Comments »'); ?></p>
</div>

I discovered last night that there was no pop-up script in my header, so I added the link for it, and I can see the script when I view my source code.

The problem is that, even though my comments settings are wide open, The whole section of the header pertaining to comments just doesn’t show.

The page I’m working with is here:

…and it’s making me crazy. Any thoughts on how to fire this baby up?
