    Script doesn't work in IE6

    Hello, I'm a javascript newb, and I have been trying to piece together a script to pop up informational divs about certain items when clicked. I found this older script on a site that works like I'd like, but didn't work in IE6. A friend offered me some advice and I tried modifying the script to get it to work in IE6, but of course, it wasn't that easy.

    I'm posting the whole page, since it isn't long, and I don't know where the problem is.

    Thanks for your help.

    I'm not sure, but I believe IE6 doesn't handle "getobj." You may want to amend this to "document.getelementbyID("idname")" or "document.getElementbyTagName("div").

    First, a basic bewilderment: why do you need an XHTML Doctype? Why not a HTML strict? Are you intend to work with XML documents? If not, an XHTML Doctype will rather confound you.

    Fixed!

    IE does not understand the width 100% and height 100% correctly with an absolutely positioned element. I have included the code to resolve this:

    width: expression(this.offsetParent.offsetWidth);
    height: expression(this.offsetParent.offsetHeight);

    Here is the code in your original post with some other minor corrections
