Show "Sorry" messages if there is no post to display

Here is my code

<?php

query_posts('cat=5&posts_per_page=3');
while (have_posts()) : the_post(); ?>
	<?php thematic_postheader(); ?>
        <div class="entry-content">
		<?php the_excerpt(); ?>
        </div>
 <?php endwhile; else: ?>
 <p>Sorry, there are currently no posts to display.</p>
 <?php endif; ?>

Really simple, but doesnt work ?? here is the error I get
Parse error: syntax error, unexpected T_ELSE in /home/content/91/8496991/html/ccomarketing/wp-content/themes/CCOTheme/homepage.php on line 40

If I take away the everything after the else: it works fine.
I have this code in a php template. What is wrong? I just want it to say sorry no posts if there arent any posts to display…
