[CSS Gradient Shadow] Custom RGB Color doesn't work on FFx

[undrline]

1) Script Title:
CSS Gradient Shadow

2) Script URL (on DD):
http://www.dynamicdrive.com/style/cs...adient-shadow/

3) Describe problem:
Changing the color seems to work fine if you have an acceptable color name ("black," "red," "blue," etc.), but creating a custom color (rrr bbb ggg) only seems to work on IE. I am testing with IE6 and FFx 3.0.10. Thank you for any assistance.

Here is the code with my modifications:
HTML

<div id="greenbox" class="shadow" rel="205 255 170">
  <p>Lorum Ipsum<br />
•&nbsp;dolor sit amet,<br />
•&nbsp;consectetur adipisicing elit,<br />
•&nbsp;sed do</p>
</div>

CSS

/*
CSS Gradient Shadow
FROM: http://www.dynamicdrive.com/style/csslibrary/item/css-gradient-shadow/
FOR: cross-browser compatible, transparent graduated shadow on containers
*/
.shadow{
	position:relative;
	display:inline;
	z-index:100;
	overflow: visible;
	background-color: #CDFFAA;
	width: 250px;
}

.shadow_inner{
	overflow: hidden;
	position: absolute;
	top: -1000px;
	filter: alpha(Opacity=10); /*modify to change the shade solidity/opacity, same as below*/
	opacity: 0.1; /*firefox 1.5 opacity*/
	-moz-opacity: 0.1; /*mozilla opacity*/
	-khtml-opacity: 0.1; /*opacity*/
	z-index: 10
}

Javascript
I added size/positioning. Gimme teh creditz!

var gradientshadow={}
gradientshadow.depth = 5 // Depth of shadow in pixels
gradientshadow.direction = "se" // Where shadow will fall.  Options: n,ne,e,se,s,sw,w,nw,center // TOFIX: center appears solid.  n,e,s,w align against topmost/leftmost rather than centered.
gradientshadow.ResizeAmount = -5 // symmetrically shrink (or grow) shadow by pixels, relative to element
gradientshadow.containers=[]

gradientshadow.create=function(){
var a = document.all ? document.all : document.getElementsByTagName('*')
for (var i = 0;i < a.length;i++) {
	if (a[i].className == "shadow") {
		for (var x=0; x<gradientshadow.depth; x++){
			var newSd = document.createElement("DIV")
			newSd.className = "shadow_inner"
			newSd.id="shadow"+gradientshadow.containers.length+"_"+x //Each shadow DIV has an id of "shadowL_X" (L=index of target element, X=index of shadow (depth) 
			if (a[i].getAttribute("rel"))
				newSd.style.background = a[i].getAttribute("rel")
			else
				newSd.style.background = "black" //default shadow color if none specified
			
			// make part of page
			document.body.appendChild(newSd)
		}
	gradientshadow.containers[gradientshadow.containers.length]=a[i]
	}
}
gradientshadow.position()
window.onresize=function(){
	gradientshadow.position()
}
}

gradientshadow.position=function(){
if (gradientshadow.containers.length>0){
	for (var i=0; i<gradientshadow.containers.length; i++){

  		var shadowdiv=document.getElementById("shadow"+i+"_"+x)
			// resize
			  shadowdiv.style.width = (gradientshadow.containers[i].offsetWidth + gradientshadow.ResizeAmount) + "px"
			  shadowdiv.style.height = (gradientshadow.containers[i].offsetHeight + gradientshadow.ResizeAmount) + "px"
			  
			// position adjustment and size
			//// options: n,ne,e,se,s,sw,w,nw,center
			//// method: push away from centered by ±x

			var oleft = gradientshadow.containers[i].offsetLeft

Anyone gonna help? I tried converting to hex instead of rgb, too. Still the same.
