I am trying to have two different posts show up on the front page. One being the latest posts and the second being posts from a single category (product review). The problem that I am having is I don't want the column with the latest posts to show up posts from the product review category. I thought I had the correct code from the codex but it is still showing up double posts. Here is the code that I have in m WP site.
<div id="rightColumn">
<strong>Side x side news</strong>
<div class="news">
<span class="top"> </span>
<?php if (have_posts()) : while (have_posts()) : the_post();
if( $post->ID == $do_not_duplicate ) continue; update_post_caches($posts); ?>
<div class="block">
<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>
<p class="date"><?php the_time('F j, Y') ?></p>
<?php the_content('Read the rest of this entry »'); ?>
<p class="comments"><?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?></p>
</div>
<?php endwhile; ?>
<div class="navigation">
<div class="alignleft"><?php next_posts_link('« Previous Entries') ?></div>
<div class="alignright"><?php previous_posts_link('Next Entries »') ?></div>
</div>
<?php else : ?>
<h2 class="center">Not Found</h2>
<p class="center">Sorry, but you are looking for something that isn't here.</p>
<?php endif; ?>
<p class="bottom">
<a href="#" class="older">Older News</a>
<a href="<?php echo get_settings('home'); ?>/?feed=rss2" class="rss">Subscribe to our news!</a>
</p></div>
<!-- PRODUCT REVIEW -->
<strong>Product Reviews</strong>
<div class="news">
<span class="top"> </span>
<?php $my_query = new WP_Query('category_name=product-review');
while ($my_query->have_posts()) : $my_query->the_post();
$do_not_duplicate = $post->ID;?>
<div class="block">
<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>
<p class="date"><?php the_time('F j, Y') ?></p>
<?php the_content('Read the rest of this entry »'); ?>
<p class="comments"><?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?></p>
</div>
<div class="navigation">
<div class="alignleft"><?php next_posts_link('« Previous Entries') ?></div>
<div class="alignright"><?php previous_posts_link('Next Entries »') ?></div>
</div>
<?php endwhile; ?>
<p class="bottom">
</p></div>
