Javascript Banner Rotator Help

[rluna559]

Hello,
I need some help getting a javascript banner rotator to work in my navibar. I place the javascript code below in my navibar. The script works fine on the root index page (CMPS) but works incorrectly on any other page.

http://www.calibersrt4.net (works correctly)

The links and links to the images appear as (http://www.calibersrt4.net/forums/http://www......

What is causing this or what am I doing wrong?

Thanks.

<SCRIPT language=JavaScript>

var img_width = "468";
var img_height = "60";
var img_title = "Visit our Sponsors!";


var ad=new Array()
//insert here your images src
ad[0]="http://www.calibersrt4.net/forums/images/sponsors/ctalogo.gif";
ad[1]="http://www.calibersrt4.net/forums/images/sponsors/mptbanner.gif";
ad[2]="http://www.calibersrt4.net/forums/images/sponsors/pracing.gif";

var links=new Array()
//insert here your links
links[0]="http://www.ctamotorsports.com";
links[1]="http://www.macellarosperformancetuning.com/";
links[2]="http://www.pracing.com";

var xy=Math.floor(Math.random()*ad.length);
document.write('<a href="'+links[xy]+'" target="_blank"><img src="'+ad[xy]+'" width="'+img_width+'" height="'+img_height+'" alt="'+img_title+'"></a>');
