Multiple Loops help

Hi, I have a sidebar before my actual page content that do a wp_query. The question is how to reset to the original query of the page so that after that wp_query it shows correctly. I.e.

<?php
	global $query_string;
	$temp_string = $query_string;
	echo $query_string;
?>
<div class="sidebar">
	<div class="block">
		<h5>Recent Post</h5>
		<ul class="recent">
			<?php
				$recent = new WP_Query("showposts=7&order=DESC&category_name=Journal");
				while($recent->have_posts()):
					$recent->the_post();
					echo '<li><a href="'.get_permalink().'">'.get_the_title().'</a></li>';
				endwhile;
			?>
		</ul>
	</div><!-- end of block -->
</div><!-- end of sidebar -->
<?php
	$query_string = $temp_string;
	query_posts($query_string);
?>

and on the content I have:

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?ptp the_title();?>
<?php endwhile; endif; ?>

As you can see i’ve tried saving the query string, but it turns out that the showposts is not saved and it gets the value from the custom wp_query, and there is no way for me to know what value I need as the sidebar is used on the single posts pages as well as on the archive pages..

Can anyone help me out…

Thanks beforehand
