Javascript newbie

I am new to javascript and am using some free code I found on the net to try to learn, so please bare with me if I do not explain thing correctly.

I downloaded a free slider menu and got it working.  The problem is the load state (or state it is in when its first loaded) is not what I expected.  

If you look at the following website

aliviarosevona.com

When it loads the sesame street image is open.  If you mouse over any image then bring your mouse out then are all collapsed, and this is how I would expect it to be when it loads.

Hope I explained this correctly.

Any help would be appreciated. Java code attached
var slideMenu=function(){
	var sp,st,t,m,sa,l,w,gw,ot;
	return{
		build:function(sm,sw,mt,s,sl,h){
			sp=s; st=sw; t=mt;
			m=document.getElementById(sm);
			sa=m.getElementsByTagName('li');
			l=sa.length; w=m.offsetWidth; gw=w/l;
			ot=Math.floor((w-st)/(l-1)); var i=0;
			for(i;i<l;i++){s=sa[i]; s.style.width=gw+'px'; this.timer(s)}
			if(sl!=null){m.timer=setInterval(function(){slideMenu.slide(sa[sl-1])},t)}
		},
		timer:function(s){
			s.onmouseover=function(){clearInterval(m.htimer);clearInterval(m.timer);m.timer=setInterval(function(){slideMenu.slide(s)},t)}
			s.onmouseout=function(){clearInterval(m.timer);clearInterval(m.htimer);m.htimer=setInterval(function(){slideMenu.slide(s,true)},t)}
		},
		slide:function(s,c){
			var cw=parseInt(s.style.width);
			if((cw<st && !c) || (cw>gw && c)){
				var owt=0; var i=0;
				for(i;i<l;i++){
					if(sa[i]!=s){
						var o,ow; var oi=0; o=sa[i]; ow=parseInt(o.style.width);
						if(ow<gw && c){oi=Math.floor((gw-ow)/sp); oi=(oi>0)?oi:1; o.style.width=(ow+oi)+'px';
						}else if(ow>ot && !c){oi=Math.floor((ow-ot)/sp); oi=(oi>0)?oi:1; o.style.width=(ow-oi)+'px'}
						if(c){owt=owt+(ow+oi)}else{owt=owt+(ow-oi)}}}
				s.style.width=(w-owt)+'px';
			}else{clearInterval(m.timer);clearInterval(m.htimer)}
		}
	};
}();

here you are ;
<script>
var slideMenu=function(){
	var sp,st,t,m,sa,l,w,gw,ot;
	return{
		build:function(sm,sw,mt,s,sl,h){
			sp=s; st=sw; t=mt;
			m=document.getElementById(sm);
			sa=m.getElementsByTagName('li');
			l=sa.length; w=m.offsetWidth; gw=w/l;
			ot=Math.floor((w-st)/(l-1)); var i=0;
			for(i;i<l;i++){s=sa[i]; s.style.width=gw+'px'; this.timer(s)}
		},
		timer:function(s){
			s.onmouseover=function(){clearInterval(m.htimer);clearInterval(m.timer);m.timer=setInterval(function(){slideMenu.slide(s)},t)}
			s.onmouseout=function(){clearInterval(m.timer);clearInterval(m.htimer);m.htimer=setInterval(function(){slideMenu.slide(s,true)},t)}
		},
		slide:function(s,c){
			var cw=parseInt(s.style.width);
			if((cw<st && !c) || (cw>gw && c)){
				var owt=0; var i=0;
				for(i;i<l;i++){
					if(sa[i]!=s){
						var o,ow; var oi=0; o=sa[i]; ow=parseInt(o.style.width);
						if(ow<gw && c){oi=Math.floor((gw-ow)/sp); oi=(oi>0)?oi:1; o.style.width=(ow+oi)+'px';
						}else if(ow>ot && !c){oi=Math.floor((ow-ot)/sp); oi=(oi>0)?oi:1; o.style.width=(ow-oi)+'px'}
						if(c){owt=owt+(ow+oi)}else{owt=owt+(ow-oi)}}}
				s.style.width=(w-owt)+'px';
			}else{clearInterval(m.timer);clearInterval(m.htimer)}
		}
	};
}();
</script>

I just removed this line ;

if(sl!=null){m.timer=setInterval(function(){slideMenu.slide(sa[sl-1])},t)}

which triggers inner method of slide that causes to slide on build .
