Insertion point doesn't work after running the report

I've used birthday list by month report and I have an insertion point that doesn't work after the report is run. I see the code in the rendered page, but it doesn't work. This is my insertion point code for teachers_nav_css.nologo.txt:

$j(document).ready(function () {
$j('iframe:not([id]').hide();
});

My workaround is to add the insertion point after this :
~[if#runreport.~[gpv:runreport]=true]

I've tried it in other insertion points but to no avail. Hoping someone has seen this before. :)
