AddThis

Follow Us Bar

Hi! I love this product! But I'm having a problem I hope you can help me with:
I've generated the code for the "Follow Us" buttons and placed it on my site, but when clicked, each button simply stays on the page on my site that the button appears on: http://www.pawpads.org/index.html.
Here is the code:
<!-- AddThis Follow BEGIN -->
<p>Follow Us on</p>
<div class="addthis_toolbox addthis_32x32_style addthis_vertical_style">
<a class="addthis_button_facebook_follow" addthis:userid="PawPADs.org"></a>
<a class="addthis_button_twitter_follow" addthis:userid="PawPADsOrg"></a>
<a class="addthis_button_youtube_follow" addthis:userid="pawpads1"></a>
</div>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#pubid=pawpads"></script>
<!-- AddThis Follow END -->

Thanks!
