looking for a bit of help here...I seem to be running in circles right now.

I am trying to write a script that will search the page for a certain ID...if said ID exists, then I want to hide a few other IDs.  this is what I have so far.

1. <script type="text/javascript">
2.     $(document).ready(function(){
3.         if($("#articleGatingWrapper")) {
4.             $("#lxTdivRating").hide();
5.             $("#commentWrapper").hide();
6.             $(".bottomArticleTools").hide();
7.             $("p.addComment").hide();
8.         });
9.     });   
10. </script>

thank you in advance for any help.
