I am using a very simple DHTML code to retrieve the navigation for all my pages, it's great.

It looks like this:

<object type="text/x-scriptlet" width="100" height="250" data="data.htm">

But it doesn't show the content in NS. Do any of you know where I could get/edit a code that is cross browser?
Or should I just put a label on my site saying: "Doesn't work in Netscape, download Internet Explorer!"
