Help my sidebar vanished

Help My right hand sidebar disappeared COMPLETELY!

I didn’t make any changes that would have caused this. At least none that i know of? I have the proper call

<?php get_sidebar();?>

in the coding. It’s not the common sidebar wrapped around to the bottom issue, it’s actually gone on all pages.

here’s the link

and my code…sans the links and ad code

<div class=”right_sidebar_container_bottom”>
<div class=”right_sidebar_single”>
<img border=”0″ width=”300″ src=”http://www.yardbarker.com/images/ybn/badge_300.gif&#8221; height=”33″/>
<?php if(is_home()) {?>

<!– End ad tag –>

<p>

<?php wp_footer(); ?>

<img src=”<?php bloginfo(‘stylesheet_directory’); ?>/promo/technorati.jpg” alt=”links” /> ” onmouseover=”domTT_activate(this, event, ‘content’, ‘My first tooltip’, ‘trail’, true);”>

<img src=”<?php bloginfo(‘stylesheet_directory’); ?>/promo/rss.jpg” alt=”links” />

</br>

<img src=”<?php bloginfo(‘stylesheet_directory’); ?>/promo/valid.jpg” alt=”links” />

</div><!– end right sidebar container wrap –>
