can anyone help?

still no answer, basically does java script not work on the portal, if not than t hat answers the question

yes it should. Did you click that a/a button before you entered that script in the custom box when you made it for the portal.

Code:

<SCRIPT>
banner0= "banner link here";
banner1= "banner link here";
banner2= "banner link here";

var ran_unrounded=Math.random()*2;
var ran_number=Math.round(ran_unrounded);

document.write(eval("banner"+ran_number));
</SCRIPT>

Just change the *2 to correspond to how many banners you want randomed. Note that 2 is actually 3, as it starts at 0.(banner0)...banner4="banner link here"; would change it to *3 and so on.
