AddThis and Adsense Code Problem

Please can someone look at this code and tell me what’s wrong with it:

<script type="text/javascript"><!--google_ad_client = "ca-pub-3767832605612747";/* 15 sep top ad */google_ad_slot = "6221489909";google_ad_width = 728;google_ad_height = 90;//--></script><script type="text/javascript"src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script><div><!-- AddThis Button BEGIN --><div class="addthis_toolbox addthis_default_style "> <div align="center"><a class="addthis_button_facebook_like" fb:like:layout="button_count"></a><a class="addthis_button_tweet"></a><a class="addthis_button_google_plusone" glusone:size="medium"></a><a class="addthis_counter addthis_pill_style"></a></div><!-- AddThis Button END --></div></div></td></td>


I want the AddThis button right under my adsense but for some reason it’s not working. Take a look at http://www.everest1953.co.uk

Thanks.
