Hi I use a magento for my e-commerce. I have custom design, but when I show my source code I can see some scripts and css styles after my footer. I want edit it but I dont know where.

<!--{%FOOTER_LINK}-->    </div>
</div>
<script type='text/javascript' src='//www.beetailer.com/javascripts/beetailer.js'></script>   <style type="text/css">
   div.share-buttons {margin-top: 5px; margin-bottom: 2px; height: 28px; vertical-align: middle; text-align: justify}
   div.share-buttons-fb-like {width: 260px;}
   div.share-custom-container {width: 260px;}
   .share-buttons-fb-like .share-custom-container span  {width: 260px !important;}
   iframe.fb_ltr {width: 260px !important;}
   div.top-container {margin-bottom: 0px;  text-align: justify}
   .header-container .top-container {margin-bottom: 0px;  text-align: justify}
   .header-container {margin-bottom: 0px;}
   div.share-buttons-og { margin-right: 5px !important;}
   .og-want {margin-top: 2px !important;}
   .og-own {margin-top: 2px !important;}
 </style>
