Single post page naviagation not working

Hiya, I’m working on a single post where I want to show a single post, and in the right colom a list with the latest 5 posts. under these post’s I want a next five posts navigation.

The showing of the single post and the latest five posts in the right colom works but The navigation does not link to the next 5 posts but it show the same five.

This is my code:

<div id=”news_left”>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<h1><?php the_title(); ?></h1>
<p><?php the_content(); ?></p>

<?php endwhile; else: ?>
<p> There is no content </p>
<?php endif; ?>
</div>
<div id=”news_right”>

<?php
$temp = $wp_query;
$wp_query = null;
$wp_query = new WP_Query();
$wp_query->query(‘category_name=news&showposts=5′.’&paged=’.$paged); ?>
<?php while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<h2>” title=”<?php the_title(); ?>”><?php the_title(); ?></h2>
<div id=”custom_img”><?php custom_field_image(); ?></div>
<div id=”intro_tekst”><span><?php the_time(‘m-y’); ?></span>
<?php the_excerpt(); ?>
</div>
<?php endwhile; ?>
<div class=”nav”><?php previous_posts_link(‘« Previous’) ?><?php next_posts_link(‘More »’) ?></div>

<?php $wp_query = null; $wp_query = $temp;?>

</div>
