Frustrating FireFox bug with ExtnernalInterface – resolved

Looks like I had a problem with my JavaScript. I need to add:
var swfDiv = document.getElementById(‘swfDiv’);

Checks out now in FireFox 3.5 mac, FireFox PC (version?), IE 8 on the pc.

<script type="text/javascript">

        function putFlashOnTop() {

                var swfDiv = document.getElementById('swfDiv');

                swfDiv.style.zIndex=3;

    }

       function putFlashOnBottom() {

                var swfDiv = document.getElementById('swfDiv');

                swfDiv.style.zIndex=1;

    }

</script>
