AddThis

Not appearing

I am a newbie and tried to enter the following to my site as the code and buttons don't appear on my pages.

<!-- AddThis Button BEGIN -->
<div class="addthis_toolbox addthis_default_style addthis_32x32_style">
<a class="addthis_button_preferred_1"></a>
<a class="addthis_button_preferred_2"></a>
<a class="addthis_button_preferred_3"></a>
<a class="addthis_button_preferred_4"></a>
<a class="addthis_button_compact"></a>
<a class="addthis_counter addthis_bubble_style"></a>
</div>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#pubid=ra-503a60c73813c0cd"></script>
<!-- AddThis Button END -->


Whereas your default code appears which is appended below

<!-- ADDTHIS BUTTON BEGIN -->
<script type="text/javascript">
var addthis_config = {
pubid: "YOUR-PROFILE-ID"
}
</script>

<a href="http://www.addthis.com/bookmark.php?v=250"
class="addthis_button"><img
src="http://s7.addthis.com/static/btn/v2/lg-share-en.gif"
width="125" height="16" border="0" alt="Share" /></a>

<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js"></script>
<!-- ADDTHIS BUTTON END -->
