Loop et scroll script

Hey,

Jeg søger lige en hurtig løsning. Jeg bruger det nedenstående js script til at scrolle med. Er det muligt at få det til, at starte forfra når man når bunden. Altså så det hele tiden looper....

//    browsercheck object
function lib_bwcheck(){ //Browsercheck (needed)
    this.ver=navigator.appVersion;
    this.agent=navigator.userAgent;
    this.dom=document.getElementById?1:0;
    this.opera5=this.agent.indexOf("Opera 5")>-1;
    this.ie5=(this.ver.indexOf("MSIE 5")>-1 && this.dom && !this.opera5)?1:0;
    this.ie6=(this.ver.indexOf("MSIE 6")>-1 && this.dom && !this.opera5)?1:0;
    this.ie4=(document.all && !this.dom && !this.opera5)?1:0;
    this.ie=this.ie4||this.ie5||this.ie6;
    this.mac=this.agent.indexOf("Mac")>-1;
    this.ns6=(this.dom && parseInt(this.ver) >= 5) ?1:0;
    this.ns4=(document.layers && !this.dom)?1:0;
    this.bw=(this.ie6 || this.ie5 || this.ie4 || this.ns4 || this.ns6 || this.opera5)
    return this;
}
var bw=new lib_bwcheck();

//    If you want it to move faster you can set this lower, it's the timeout:
var speed = 20;

//    Sets variables to keep track of what's happening
var loop, timer;

//    Element Object
function makeObj(obj,nest){
    nest=(!nest) ? "":'document.'+nest+'.';
    this.el=bw.dom?document.getElementById(obj):bw.ie4?document.all[obj]:bw.ns4?eval(nest+'document.'+obj):0;
      this.css=bw.dom?document.getElementById(obj).style:bw.ie4?document.all[obj].style:bw.ns4?eval(nest+'document.'+obj):0;
    this.scrollHeight=bw.ns4?this.css.document.height:this.el.offsetHeight;
    this.clipHeight=bw.ns4?this.css.clip.height:this.el.offsetHeight;
    this.up=goUp;this.down=goDown;
    this.moveIt=moveIt; this.x=0; this.y=0;
    this.obj = obj + "Object";
    eval(this.obj + "=this");
    return this
}

// A unit of measure that will be added when setting the position of a layer.
var px = bw.ns4||window.opera?"":"px";

function moveIt(x,y){
    this.x = x
    this.y = y
    this.css.left = this.y+px
    this.css.top = this.x+px
}

//Makes the object go up
function goDown(move){
    if (this.y>-this.scrollHeight+oCont.clipHeight){
        this.moveIt(0,this.y-move)
            if (loop) setTimeout(this.obj+".down("+move+")",speed)
    }
}
//Makes the object go down
function goUp(move){
    if (this.y<0){
        this.moveIt(0,this.y-move)
        if (loop) setTimeout(this.obj+".up("+move+")",speed)
    }
}

//Calls the scrolling functions. Also checks whether the page is loaded or not.
function scroll(speed){
    if (scrolltextLoaded){
        loop = true;
        if (speed>0) oScroll.down(speed)
        else oScroll.up(speed)
    }
}

//Stops the scrolling (called on mouseout)
function noScroll(){
    loop = false
    if (timer) clearTimeout(timer)
}

//Makes the object
var scrolltextLoaded = false
function scrolltextInit(lmnt, srll){
    if(document.getElementById(lmnt)){
        oCont = new makeObj(lmnt);
        oScroll = new makeObj(srll,lmnt);
        oScroll.moveIt(0,0);
        oCont.css.visibility = "visible";
        scrolltextLoaded = true;
    }
}


function initScrollable(lmnt, srll){
    if (bw.bw) scrolltextInit(lmnt, srll);
}
