Hallo, habe mal eine Frage. Ich wollte wieder Schnneflocken auf meine Homepage zaubern. Vorriges Jahre habe ich das irgend wie hinbekommen. Jetzt gelingt es nicht mehr :-((

Kann mit wer helfen? Ich habe folgenden Quellcode aus dem Internet:

<script language="JavaScript" type="text/javascript">
<!--
var numImages = 1;
var numFlakes = 20;
var ns  = (document.layers)?1:0;
var ns6 = (document.getElementById&&!document.all)?1:0;
var opera5 = (navigator.userAgent.indexOf("Opera") > -1 && document.getElementById) ? 1:0;
var winWidth  = (ns||ns6||opera5)?window.innerWidth-70:window.document.body.clientWidth;
var winHeight = (ns||ns6||opera5)?window.innerHeight:window.document.body.clientHeight;
var flakeX = new Array();
var flakeY = new Array();
var flakeSpeed = new Array();
var flakeStep  = new Array();
var flakeStep2 = new Array();
for (i=0; i<numImages; i++)
{
eval('imgFlake' + i + '=new Image();');
eval('imgFlake' + i + '.src="http://www.iphpbb.com/board/images/snowsmall.gif";');
}
if (ns)
{
for (i=0; i<numFlakes; i++)
{
eval('var picSource=imgFlake' + Math.floor(Math.random()*numImages) + '.src;');
document.write('<LAYER name="layerFlake' + i + '" left="0" top="0"><IMG src="' + picSource + '"></LAYER>');
}
} else {
document.write('<DIV style="position:absolute;top:0px;left:0px"><DIV style="position:relative">');
for (i=0; i<numFlakes; i++)

}
document.write('</DIV></DIV>');
}
for (i=0; i<numFlakes; i++)
{
flakeX[i] = Math.round(Math.random()*winWidth);
flakeY[i] = Math.round(Math.random()*winHeight);
flakeSpeed[i] = Math.random()*3+3;
flakeStep[i]  = Math.random()*0.1+0.05;
flakeStep2[i] = 0;
}
function fLetItSnow()
{
var winWidth  = (ns||ns6||opera5)?window.innerWidth-70:window.document.body.clientWidth;
var winHeight = (ns||ns6||opera5)?window.innerHeight:window.document.body.clientHeight;

for (i=0; i<numFlakes; i++){
speedX = flakeSpeed[i]*Math.cos(flakeStep2[i])/2;
speedY = flakeSpeed[i]*Math.sin(90*Math.PI/180);
flakeX[i] += speedX;
flakeY[i] += speedY;
if (flakeY[i]>winHeight)
{
flakeX[i]=Math.round(Math.random()*winWidth);
flakeY[i]=-100;
flakeSpeed[i]=Math.random()*3+3;
}
if (ns)
{

document.layers['layerFlake' + i].top  = flakeY[i] + hscrll;
} else if (ns6||opera5) {

}
flakeStep2[i]+=flakeStep[i];
}
setTimeout('fLetItSnow()', 20);
}

Viele Dank
