Hi I have a very simple js rollover nav bar which is giving me probs.. It used to work fine but as I have changed the site I am wondering if I have messed up part of the js code ?

Can anyone take a look through it please.. many thanks..

BTW this code is NOT in the head... does it have to be ?

<script language=JavaScript>
<!--
if(document.images) {

var img1on = new Image();
img1on.src = 'images/nav/homeon.gif';
var img2on = new Image();
img2on.src = 'images/nav/sitemapon.gif';
var img3on = new Image();
img3on.src = 'images/nav/abouton.gif';
var img4on = new Image();
img4on.src = 'images/nav/advertiseon.gif';
var img5on = new Image();
img5on.src = 'images/nav/contacton.gif';





var img1off = new Image();
img1off.src = 'images/nav/homeoff.gif';
var img2off = new Image();
img2off.src = 'images/nav/sitemapoff.gif';
var img3off = new Image();
img3off.src = 'images/nav/aboutoff.gif';
var img4off = new Image();
img4off.src = 'images/nav/advertiseoff.gif';
var img5off = new Image();
img5off.src = 'images/nav/contactoff.gif';



}
function imgOn(imgName) {
if (document.images) {
document[imgName].src = eval(imgName + 'on.src;');
}
}

function imgOff(imgName) {
if (document.images) {
document[imgName].src = eval(imgName + 'off.src;');
}
}
//-->
</script>

AND HERE IS THE NAV BAR ITSELF..
