comments_number not displaying

Question

Live site

I'm using <?php comments_number( $zero, $one, $more ); ?> on home.php to display number of comments in the post-meta. Problem is, it's not showing the number despite there being one comment on that post. Any ideas what's causing the problem?

Here's post-meta for index.php:

<div class="post-meta">
                <p><?php the_date(); ?> | <?php the_tags('tags:', ', ', '<br />'); ?> | <?php comments_number( $zero, $one, $more ); ?> comments</p>
                <?php comments_template(); ?>
            </div><!-- end post-meta -->

Answer 1

You need to change the code you're using from

<div class="post-meta">
    <p><?php the_date(); ?> | <?php the_tags('tags:', ', ', '<br />'); ?> | <?php comments_number( $zero, $one, $more ); ?> comments</p>
    <?php comments_template(); ?>
</div><!-- end post-meta -->

to

<div class="post-meta">
    <p><?php the_date(); ?> | <?php the_tags('tags:', ', ', '<br />'); ?> | <?php comments_number( 'no responses', 'one response', '% responses' ); ?> comments</p>
    <?php comments_template(); ?>
</div><!-- end post-meta -->

you need to replace $zero, $one, and $more with your own code; read the example in the Codex: http://codex.wordpress.org/Function_Reference/comments_number#Examples
