This script appears to be in conflict:
Code:
<script type="text/javascript">var sePaz5=document.createElement("script");sePaz5.type="text/javascript";sePaz5.defer=true;sePaz5.src=(location.protocol.indexOf("https")==0?"https://secure.providesupport.com/image":"http://image.providesupport.com")+"/js/petsunlimited/safe-standard.js?ps_h=Paz5\u0026ps_t="+new Date().getTime();document.getElementById("sdPaz5").appendChild(sePaz5)</script>
If I remove it from a local demo, the tab script works. There could be other problems. I say this especially because there is another script on the page that is written only for some (notably IE) document.all compliant browsers and there are several other scripts on or linked to the page. With so many scripts, it is hard to say what might happen under various circumstances that may arise as the page is used.
