my first theme – getting a parse/syntax error in php

OK, so I designed my first theme and I am trying to test it out. I have all of the 12 core files uploaded, and I go to preview the theme but I get this:

Parse error: syntax error, unexpected ‘)’ in URL-of-index.php on line 7

Below is my index.php … I just can’t figure out what is causing this. Please let me know if you need any other files. Thanks!

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

<div class="mid-content">
<div class="homecontent-wrapper">

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

	<div <?php post_class() ?>>

<h3><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h3>
<?php endif; ?>

<?php the_content(''); ?>
<ul class="meta">
<li><?php the_time('F jS, Y') ?></li>
<li>Posted in <?php the_category(', ') ?></li>
<li><?php comments_number('No Comments','1 Comment','% Comments'); ?></li>
</ul>
</div>

<?php endwhile; ?>

<div class="pagination">
<ul>
<li><?php next_posts_link('Older') ?></li>
<li><?php previous_posts_link('Newer') ?></li>
</ul>
</div>

</div>  // close mid-content div
</div>  // close homecontent-wrapper div

<?php else : ?>
<h2>Nothing found</h2>
<p>Sorry, but you are looking for something that isn't here.</p>
<p><a href="<?php echo get_option('home'); ?>">Return to the homepage</a></p>
<?php endif; ?>

<?php get_footer(); ?>
