Fixed positioning an ad in IE

Can skip to the edit for a more up to date explanation.

I can't seem to set an ad that gets written out via document.write() to a fixed position. It works fine in all other browsers besides IE, and that includes IE9.

Here is an example: http://htinteractive.com/bottom_bar/demo.html

Any suggestions would be highly appreciated. I'm running out of ideas.

Thank you.

Edit:

I've narrowed the problem down to the following IE issue I'm having. To simplify it down...

<style type="text/css">
    #temp1
    {
        position:fixed; 
        bottom:0; 
        height:100px; 
        width:100px; 
        border:solid 2px red;
    }
</style>

<!--WORKS IN IE-->
<div id="temp1">
    <script type="text/javascript">
        document.write("<scr" + "ipt type=\"text/javascript\">\nif(typeof(cachebuster) == \"undefined\"){var cachebuster = Math.floor(Math.random()*10000000000)}\nif(typeof(dcopt) == \"undefined\"){var dcopt = \"dcopt=ist;\"} else {var dcopt = \"\"}\nif(typeof(tile) == \"undefined\"){var tile = 1} else {tile++}\ndocument.write('<scr'+'ipt src=\"http://ad.doubleclick.net/adj/shz.bloomington/home;pos=728x90_1;' + dcopt + ';tile=' + tile + ';sz=728x90;ord=' + cachebuster + '?\"></scr'+'ipt>');\n</scr" + "ipt>");
    </script>
</div>

    document.write("<scr" + "ipt type=\"text/javascript\">\nif(typeof(cachebuster) == \"undefined\"){var cachebuster = Math.floor(Math.random()*10000000000)}\nif(typeof(dcopt) == \"undefined\"){var dcopt = \"dcopt=ist;\"} else {var dcopt = \"\"}\nif(typeof(tile) == \"undefined\"){var tile = 1} else {tile++}\ndocument.write('<scr'+'ipt src=\"http://ad.double
