Error: unexpected $end

Hi there, I’m trying to add a featured post area to my blog, and I did the following code:

<?php $my_query = new WP_Query('category_name=Floreria&showposts=1');
 while ($my_query->have_posts()) : $my_query->the_post(); $do_not_duplicate = $post->ID; ?>
  <div id="feature">
    <h2 class="post-title">
    	<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
    </h2>
    	<?php the_excerpt(); ?>
    	<?php edit_post_link(__('Editar'), ", ' | '); ?>
  </div>
<?php endwhile; ?>

But I can’t figure why I’m getting this error:

Parse error: syntax error, unexpected $end in ******/floreria.php on line 10

If someone could help me figure it out.

Thanks
