Troubleshooting IOL Hide function

I�ve been doing my best to locate the correct id using the developer tools, but this fella just keeps popping up.

(function(){

 $('img[qbu=module]').remove();

 $('img[qbu=module]').hide();

var querystring=document.location.search;

 if(/a=er/i.test(querystring)) {                

                $(".IconOnly, #saveButton").hide();

                $(".IconOnly, #saveMenu").hide();

                $(".IconOnly, #cancelButton").hide();

                $(".IconOnly, #footerSaveButton").hide();

                $(".IconOnly, #footerCancelButton").hide();

                $("span.Icon.DownArrowWhite").hide()

                }

else if(/a=dr/i.test(querystring)) {

              ... and so on
