Adding HTML Banner to Enfold Theme

Hi,
I’m having problems adding an HMTL Banner to my website. Here’s the code:

<div id="allianzBannerEmbed">
    <script src="http://allianz-vor-ort.de/js/allianzTeaserEmbed.js" type="text/javascript"></script>
    <script type="text/javascript">
        embedSWF("7383", "728", "90");
    </script>
    <div id="container" style="width: 728px; height: 90px;">
        <div id="flashcontent"><script type="text/javascript">embedGif("7383");</script></div>
    </div>
</div>

I tried to put it in the code-section and a text-section. Non of these worked.

Regards
Damian
