Parse error: syntax error, unexpected T_ELSE

page.php
—————————-
<?php get_header(); ?>
<div id=”content”>

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

<div class=”post” id=”post-<?php the_ID(); ?>”>
<h2><?php the_title(); ?></h2>
<span class=”post-cat”><?php the_category(‘, ‘) ?></span>
</div>
<div class=”entry”>
<?php the_content(‘<p class=”serif”>Read the rest of this page »</p>’); ?>

<?php wp_link_pages(array(‘before’ => ‘<p>Pages: ‘, ‘after’ => ‘</p>’, ‘next_or_number’ => ‘number’)); ?>
</div>

<?php comments_template(); ?>
</div>

<?php endwhile; endif; ?>

<div class=”navigation”>
<span class=”previous-entries”><?php previous_post_link(‘%link’)?></span>
<span class=”next-entries”><?php next_post_link(‘%link’)?></span>
</div>

<?php else : ?>

<h2>Not Found</h2>
<p>Sorry, but you are looking for something that isn’t here.</p>

<?php endif; ?>

</div>
<!–/content –>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

It says I have an unexpected parse error of T_ELSE on line 26 which is
<?php else : ?>

Any help would be great.
