binding with prototype

I am new to prototype, thought it would be easiest way to accomplish cross browser compatibility... but alas, syntax escapes me in binding! Heeeeres... my code!

function OrbCreator(){
	var b = new Element('img',{src: '../images/Orb.png', position: 'absolute', display: 'none', left: '10000px', top: '0px', width: '100px', height: '100px', zIndex: '0'});
	$('container').insert(b);
	this.set=setAttribute(b,);
}
 
function moveOrb(x,y,z){
	left=x-Os;
	top=y-Os;
	zIndex=z;
	height=Os;
	width=Os;
	opacity=1/z;
	display='block';
	[COLOR="Red"]this.set=display:display,left:left,top:top,width:width,height:height,zIndex:zIndex,opacity:opacity;[/COLOR]
	if(renew=2){
		this.set({src:"../images/NewImage.png"});
	}
	if($('message').getStyle('top')>0){
 		writeAttribute("message",{top: top++})
	}
}

So slap me silly and call me names, but what am I doing wrong and please, very importantly... why is it wrong and what is right, why?

 

Having a little success with this code:

function OrbCreator(){
	var b = new Element('img',{src: '../images/Orb.png', position: 'absolute', display: 'none', left: '10000px', top: '0px', width: '100px', height: '100px', zIndex: '0'});
	$('container').insert(b);
	this.img=b;
	this.move=moveOrb;
}
 
function moveOrb(x,y,z){
	Left=x-Os;
	Top=y-Os;
	ZIndex=z;
	Height=Os;
	Width=Os;
	Opacity=1/z;
	Display='block';
	this.img.setAttribute(this.img,{display:Display,left:Left,top:Top,width:Width,height:Height,zIndex:ZIndex,opacity:Opacity});
	if(renew=2){
		this.img.setAttribute({src:"../images/NewImage.png"});
	}
	if($('message').getStyle('top')>0){
 		writeAttribute("message",{top: top++})
	}
}

Code (markup):

firebug error is "String contains an invalid character" code: "5
[Break on this error] this.img.setAttribute(this.img,{display...:Height,zIndex:ZIndex,opacity:Opacity});"
