next_posts_link and previous_posts_link malfunction

Hi all,

My issue is that next_posts_link and previous_posts_link works on the category page but not on the customized recent blogs page. It shows only the recent 5 posts and displays the same even if I click on older or newer entries link. Plz help. Here is the code for recent blogs custom page

<?php query_posts("posts_per_page=5"); ?>
	<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

		<div <?php post_class() ?> id="post-<?php the_ID(); ?>">

			<h4><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h4>

			<?php include (TEMPLATEPATH . '/inc/meta.php' ); ?>

			<div class="entry">
				<?php the_excerpt(); ?>
			</div>

		</div>

	<?php endwhile; ?>

	<?php include (TEMPLATEPATH . '/inc/nav.php' ); ?>

	<?php else : ?>

		<h2>Not Found</h2>

	<?php endif; ?>

And nav.php code is

<div class="navigation">
	<div class="next-posts"><?php next_posts_link('? Older Entries') ?></div>
	<div class="prev-posts"><?php previous_posts_link('Newer Entries ?') ?></div>
</div>

I ‘d appreciate any help.

Thanks and have a nice day>
