Creating HTML Offer for Global Mbox

Hello,

I'm trying to create an HTML Offer in Target Classis to be used in a global mbox.  It's supposed to change the navigation with a different URLs and names for the navigation.  I tried creating the following offer, but all I'm getting is that the current navigation gets hidden:

<style>
#navigation {visibility:hidden};
</style>

<script type="text/javascript">

$('#navigation').html('<li>
                    <a href="index.html">Home</a>
                </li>
                <li class="active">
                    <a href="features.html">Features - New</a>
                </li>
                <li>
                    <a href="news.html">News - Offer</a>
                </li>
                <li>
                    <a href="about.html">About Us</a>
                </li>
                <li>
                    <a href="contact.html">Contact Us</a>
                </li>');

</script>

The page where I'm running this test is http://test.manzanet.us/features.html

Any guidance on how I can do this will be greatly appreciated because I'm stuck.

Thanks,
