I am using this page number plugin (this is the site):

http://www.jenst.se/2008/03/29/wp-page-numbers

Below is the lower part of my Archives (archive.php) where I thought I put the right code
Can you please tell me if it looks right
I've been working on this problem for over a week and the wordpress forum is not helping me out
I can't figure out why my blog doesn't show the page numbers. I don't understand what I am supposed to change in the settings page number section either? Am I supposed to unclick something?
I hope I didn't confuse people too much:
-------------------------------------------------------------------------------------------------------------
class="postmetadata"><?php the_tags('Tags: ', ', ', '<br />'); ?></p><?php } ?>

</div>

<?php endwhile; ?>

<div class="navigation">
<!-- <div class="alignleft"><?php if(function_exists('wp_page_numbers')) { wp_page_numbers(); } ?>) ?></div>
<div class="alignright"><?php if(function_exists('wp_page_numbers')) { wp_page_numbers(); } ?>) ?></div>
</div>-->
<?php if(function_exists('wp_page_numbers')) { wp_page_numbers(); } ?>

</div>

<?php else : ?>

<h2 class="center">Not Found</h2>
<?php include (TEMPLATEPATH . '/searchform.php'); ?>

<?php endif; ?>

</div>

<?php get_sidebar(); ?>
</div>
<?php get_footer(); ?>

What version of WP, Atahualpa and PHP?
Whart is the url showing the issue?

Is this something like the WP-Pagenavi plugin? If so I'd suggest to use WP-Pagenav because Atahualpa is prepared for that and you don't need to edit files
