Exclude current post when displaying recent posts in sidebar

Hello,

I’m having trouble trying to exclude the current post from my other posts sidebar. My code is as following.

The Main Post

`
<div id=”col_1″>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<div id=”col_1_top”>
<h5>“><?php the_title(); ?></h5>
</div>
<div id=”col_1_bod”>
<p><?php the_content(); ?></p>
</div>
<?php endwhile; ?>
<?php endif; ?>
</div>

The Recent Posts

<div id=”col_2″>
<div id=”col_2_top”>
<h5>Other Notices</h5>
</div>
<div id=”col_2_bod”>
<?php query_posts(‘category_name=Notice&showposts=4’); ?>
<?php while (have_posts()) : the_post(); ?>
<div class=”col_item”>
<h5>“><?php the_title(); ?></h5>
<p><?php the_content(); ?></p>
</div>
<?php endwhile; ?>
<?php wp_reset_query(); ?>
</div>
</div>
