How to get share and buttons on the right side of the page?

Our test page: http://test.piedmonthealth.org/news/piedmont-health-physicians-wunc-radio

Here is my code (which defaults to the left side of the page). How do I get it to STAY on the right side of the page? Nothing I do seems to work!

<!-- AddThis Button BEGIN -->
<div class="addthis_toolbox addthis_default_style ">
<a href="http://www.addthis.com/bookmark.php?v=250&amp;pubid=ra-4f9d3c2f63edabc5" class="addthis_button_compact">Share</a>
<span class="addthis_separator">|</span>
<a class="addthis_button_print"></a>
<span class="addthis_separator">|</span>
<a class="addthis_button_email"></a>
<span class="addthis_separator">|</span>
<a class="addthis_button_facebook"></a>
<span class="addthis_separator">|</span>
<a class="addthis_button_twitter"></a>
</div>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#pubid=ra-4f9d3c2f63edabc5"></script>
<!-- AddThis Button END -->
