Nice and helpfull Script !!

... I am not able to bring the script works correctly with 3 nested tabs

<script type="text/javascript">

var countries_1=new ddajaxtabs("countrytabs_1", "countrydivcontainer_1");
countries_1.setpersist(false);
countries_1.setselectedClassTarget("link"); //"link" or "linkparent"
countries_1.init();

countries_1.onajaxpageload=function(pageurl){

 if (pageurl.indexOf("/admin/esercizi/esercizi.inc.php")!=-1){
  sedondLevelTab_1=new ddajaxtabs("tabsMain_84", "tabsMainContainer_84");
  sedondLevelTab_1.setpersist(false);
  sedondLevelTab_1.setselectedClassTarget("link"); //"link" or "linkparent"
  sedondLevelTab_1.init();
 }
 
 else if (pageurl.indexOf("/admin/esercizi/esercizi_offerteAjaxTabs.php")!=-1){
  thirdLevelTab_1=new ddajaxtabs("tabsOfferte_84", "offerteContainer_84");
  thirdLevelTab_1.setpersist(false);
  thirdLevelTab_1.setselectedClassTarget("link"); //"link" or "linkparent"
  thirdLevelTab_1.init();
 }

}

</script>

The script works only with 2 nested tabs ...

Any ideas if this is a script issue or if I have not correctly configured the script ?

Thank you

There's no reason why the script only works with 2 nested tabs, and not 3. Please post a link to the page on your site that contains the problematic script so we can check it out.
