Falling Leaves

I'm trying to add falling leaves to my website. I've found a JS code that seemingly has worked for people in the past but that doesn't seem to be the case for me. I have tried placing it in my templates and I get nothing.

Here is the code:

Code:

<script language="JavaScript1.2">
 
//Autumn leaves- by Kurt Grigg (kurt.grigg@virgin.net)
//Modified by Dynamic Drive for NS6 functionality
//visit http://www.dynamicdrive.com for this script
 
//Pre-load your image below!
grphcs=new Array(6)
Image0=new Image();
Image0.src=grphcs[0]="http://www.dynamicdrive.com/dynamicindex3/al.gif";
Image1=new Image();
Image1.src=grphcs[1]="http://www.dynamicdrive.com/dynamicindex3/bl.gif"
Image2=new Image();
Image2.src=grphcs[2]="http://www.dynamicdrive.com/dynamicindex3/cl.gif"
Image3=new Image();
Image3.src=grphcs[3]="http://www.dynamicdrive.com/dynamicindex3/dl.gif"
Image4=new Image();
Image4.src=grphcs[4]="http://www.dynamicdrive.com/dynamicindex3/el.gif"
Image5=new Image();
Image5.src=grphcs[5]="http://www.dynamicdrive.com/dynamicindex3/fl.gif"
 
Amount=8; //Smoothness depends on image file size, the smaller the size the more you can use!
Ypos=new Array();
Xpos=new Array();
Speed=new Array();
Step=new Array();
Cstep=new Array();
ns=(document.layers)?1:0;
ns6=(document.getElementById&&!document.all)?1:0;
 
if (ns){
for (i = 0; i < Amount; i++){
var P=Math.floor(Math.random()*grphcs.length);
rndPic=grphcs[P];
document.write("<LAYER NAME='sn"+i+"' LEFT=0 TOP=0><img src="+rndPic+"></LAYER>");
}
}
else{
document.write('<div style="position:absolute;top:0px;left:0px"><div style="position:relative">');
for (i = 0; i < Amount; i++){
var P=Math.floor(Math.random()*grphcs.length);
rndPic=grphcs[P];
document.write('<img id="si'+i+'" src="'+rndPic+'" style="position:absolute;top:0px;left:0px">');
}
document.write('</div></div>');
}
WinHeight=(ns||ns6)?window.innerHeight:window.document.body.clientHeight;
WinWidth=(ns||ns6)?window.innerWidth-70:window.document.body.clientWidth;
for (i=0; i < Amount; i++){                                                             
 Ypos[i] = Math.round(Math.random()*WinHeight);
 Xpos[i] = Math.round(Math.random()*WinWidth);
 Speed[i]= Math.random()*5+3;
 Cstep[i]=0;
 Step[i]=Math.random()*0.1+0.05;
}
function fall(){
var WinHeight=(ns||ns6)?window.innerHeight:window.document.body.clientHeight;
var WinWidth=(ns||ns6)?window.innerWidth-70:window.document.body.clientWidth;
var hscrll=(ns||ns6)?window.pageYOffset:document.body.scrollTop;
var wscrll=(ns||ns6)?window.pageXOffset:document.body.scrollLeft;
for (i=0; i < Amount; i++){
sy = Speed[i]*Math.sin(90*Math.PI/180);
sx = Speed[i]*Math.cos(Cstep[i]);
Ypos[i]+=sy;
Xpos[i]+=sx;
if (Ypos[i] > WinHeight){
Ypos[i]=-60;
Xpos[i]=Math.round(Math.random()*WinWidth);
Speed[i]=Math.random()*5+3;
}
if (ns){
document.layers['sn'+i].left=Xpos[i];
document.layers['sn'+i].top=Ypos[i]+hscrll;
}
else if (ns6){
document.getElementById("si"+i).style.left=Math.min(WinWidth,Xpos[i]);
document.getElementById("si"+i).style.top=Ypos[i]+hscrll;
}
else{
eval("document.all.si"+i).style.left=Xpos[i];
eval("document.all.si"+i).style.top=Ypos[i]+hscrll;
}
Cstep[i]+=Step[i];
}
setTimeout('fall()',20);
}
 
window.onload=fall
//-->
</script>

One thing I noticed is that no matter where I placed it the last '</script>' was colored red. I have tried with both the images included in this script and images of my own.

Any help is appreciated, thank you! Here is my site for reference: http://projectcrusade.forumotion.com/

You can use the image rain codes and replace the images with leaves.

That works, thanks. I just wish they fell continuously instead of once (Seems to be the case, nevermind) and had a variety of images like the code in my original post.
