Need help with script

[juuso79]

I found this great scrolling script. It's allmost perfect but It doest stop scrolling down when the page ends. So If someone better java programmer could help me and modify this script so the scolling ends when the page ends I would be very gratefull.

<!-- Begin
function verScroll(dir, spd, loop) {
loop = true;
direction = &quot;up&quot;;
speed = 10;
scrolltimer = null;
if (document.layers) {
var page = eval(document.contentLayer);
}
else {
if (document.getElementById) {
var page= eval(&quot;document.getElementById('contentLayer').style&quot;
}
else {
if (document.all) {
var page = eval(document.all.contentLayer.style);
}
}
}
direction = dir;
speed = parseInt(spd);
var y_pos = parseInt(page.top);
if (loop == true) {
if (direction == &quot;dn&quot {
page.top = (y_pos - (speed));
} else {
if (direction == &quot;up&quot; && y_pos < 10) {
page.top = (y_pos + (speed));
} else {
if (direction == &quot;top&quot {
page.top = 10;
}
}
}
scrolltimer = setTimeout(&quot;verScroll(direction,speed)&quot;, 1);
}
}
function stopScroll() {
loop = false;
clearTimeout(scrolltimer);
}
// End -->


<div id=&quot;scrollmenu&quot; style=&quot;position:absolute;width:200px;height:30px;z-index:1; left:400px; top: 40px&quot;>

<table><tr><td>
<a href=&quot;#&quot; onMouseOver=&quot;verScroll('dn','5','true')&quot; onMouseOut=&quot;stopScroll()&quot;>>></a>
