Page_blog problem

Hey there, I have edited my page_blog.php to display 8 articles (french and arabic) and it’s working but the problem is when you click on “Next Page” it’ll take you to page 2/3/4/5/6 but the articles are not changing, even though I have more than 8 articles posted on my site.

This is my site: [LINK] (pass guest/guest)

This is the code page_blog.php

<?php $page = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("showposts=4&amp;paged=$page"); while ( have_posts() ) : the_post() ?>

            <?php
				$arabic="";
				foreach((get_the_category()) as $category) {
				if($category->cat_name=="Arabic"){
				$arabic='1';
				echo '<div style="text-align:right;">';
				} }
				?>
		<h1><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h1>
		<?php if($arabic=="1"){ the_excerpt_rereloaded('200','<strong>???????</strong>','<a>,<i>,<em>,<b>,<strong>,<ul>,<ol>,<li>,<span>,<blockquote>','plain'); } else{ the_excerpt_rereloaded('50','<strong>Suite</strong>','<a>,<i>,<em>,<b>,<strong>,<ul>,<ol>,<li>,<span>,<blockquote>','plain');} ?>
        				<div class="hpfeedmeta">
					<p><?php the_time('j F, Y'); ?> | <?php comments_popup_link('Aucun commentaire', '1 Commentaire', '% Commentaires'); ?></p>
				</div>
                <?php
				if($arabic=="1"){
				echo '</div>';
				}
				?>

			<div class="postmeta2">
				Tagged: <?php the_tags('') ?>
			</div>

			<?php endwhile; ?>

			<p align="right"><strong><?php
			 if(get_query_var('paged')=='2'){
			 echo '<a href="/">&laquo; Accueil</a> | ';
			 next_posts_link('Page Suivante &raquo;');
			 }else{
			 posts_nav_link(' | ', '&laquo; Page Précédente', 'Page Suivante &raquo;');
			 }
			 ?></strong></p>

Please tell me what am I doing wrong here?
