“Comments are closed.” not displaying

Hello, I am going thru the default theme of wordpress 2.9.2; and when I closed the comments the line “Comments are closed.” is not displaying.

here is the code of comments.php of default theme.

<?php else : // this is displayed if there are no comments so far ?>

	<?php if ( comments_open() ) : ?>
		<!-- If comments are open, but there are no comments. -->

	 <?php else : // comments are closed ?>
		<!-- If comments are closed. -->
		<p class="nocomments">Comments are closed.</p>

	<?php endif; ?>
<?php endif; ?>

Please help me.
