}

og her er mit java script :

<style type="text/css">

</style>
<SCRIPT LANGUAGE="JavaScript1.2">

chanceAd=1; // ad will be shown 1 in X times (put 1 for everytime)

var ns=(document.layers);

adCount=0;
function initAd(){
    if(!ns && !ie && !w3) return;
    if(ie)        adDiv=eval('document.all.sponsorAdDiv.style');
    else if(ns)    adDiv=eval('document.layers["sponsorAdDiv"]');
