“Previous&Next” doesn’t work

Hi guys,
I’ve some problem on my blog https://www.zerogradinord.net: Pevious&Next button doesn’t work. When you click on it the permalink change like you’re visiting the second page, third, fourth and so on, but you can read all the time the home page.
This is the code of the index page:

<?php get_header(); ?>

<style>

#divSWD{

background-color:#000000;

height: 120px;

width: 90%;

border:1px solid #FFFFFF;

font-family: Arial, Helvetica, sans-serif;

color: #FFFFFF;

left: 5%;

position:relative;

top:3px;

}

</style>

<div id=”divSWD”><?php include(“swd_carousel_nuovo.php”) ?></div>

<?php get_sidebar(); ?>

<?php include (TEMPLATEPATH . ‘/right-sidebar.php’); ?>

}

<?php while (have_posts()) : the_post(); ?>

<?php endwhile; ?>

<div class=”alignright”><?php previous_posts_link(__(‘Next Entries »’,’andreas09′)) ?></div>

</div>

<?php else : ?>

<div id=”page”>

<h1 class=”center”><?php _e(‘Not Found’,’andreas09′); ?></h1>

<p class=”center”><?php _e(‘Sorry, but you are looking for something that isn\’t here.’,’andreas09′); ?></p>

</div>

<?php endif; ?>

</div>

<?php get_footer(); ?>

Some suggestions?
