Fade af billeder - fejl

Hej Eksperter..

Jeg er ved at lave følgene side hvor der er en fejl på...!
http://www.muleen.dk/host/sedr2/

scriptet ser således ud:...

<script>
var slideshow_width=300  // Definer billedbredde
var slideshow_height=170 // Definer billedhøjde
var pause=3000          // Definer tid i tusindedele sekund
var fade=50            // Definer fade hastigheed

var fadeimages=new Array()
fadeimages[0]="img/dr1.gif"
fadeimages[1]="img/dr2.gif"
fadeimages[2]="img/tv2.gif"

var preloadedimages=new Array()
for (p=0;p<fadeimages.length;p++){
preloadedimages[p]=new Image()
preloadedimages[p].src=fadeimages[p]
}

var ie4=document.all&&navigator.userAgent.indexOf("Opera")==-1
var dom=document.getElementById&&navigator.userAgent.indexOf ("Opera")==-1

if (ie4||dom)
document.write('<div style="position:relative;width:'+slideshow_width+';height:'+ slideshow_height+';overflow:hidden"><div id="canvas0" style="position:absolute;width:'+slideshow_width+';height:'+ slideshow_height+';top:0;filter:alpha(opacity=10);-moz-opacity:10"></div><div id="canvas1" style="position:absolute;width:'+slideshow_width+';height:'+ slideshow_height+';top:0;filter:alpha(opacity=10);-moz-opacity:10"></div></div>')
else
document.write('<img name="defaultslide" src="'+fadeimages[0]+'">')

var curpos=10
var degree=10
var curcanvas="canvas0"
var curimageindex=0
var nextimageindex=1


function fadepic(){
if (curpos<100){
curpos+=10
if (tempobj.filters)
tempobj.filters.alpha.opacity=curpos
else if (tempobj.style.MozOpacity)
tempobj.style.MozOpacity=curpos/100
}
else{
clearInterval(dropslide)
nextcanvas=(curcanvas=="canvas0")? "canvas0" : "canvas1"
tempobj=ie4? eval("document.all."+nextcanvas) : document.getElementById(nextcanvas)
tempobj.innerHTML='<img src="'+fadeimages[nextimageindex]+'">'
nextimageindex=(nextimageindex<fadeimages.length-1)? nextimageindex+1 : 0
setTimeout("rotateimage()",pause)
}
}

function rotateimage(){
if (ie4||dom){
resetit(curcanvas)
var crossobj=tempobj=ie4? eval("document.all."+curcanvas) : document.getElementById(curcanvas)
crossobj.style.zIndex++
var temp='setInterval("fadepic()",50)'
dropslide=eval(temp)
curcanvas=(curcanvas=="canvas0")? "canvas1" : "canvas0"
}
else
document.images.defaultslide.src=fadeimages[curimageindex]
curimageindex=(curimageindex<fadeimages.length-1)? curimageindex+1 : 0
}

function resetit(what){
curpos=10
var crossobj=ie4? eval("document.all."+what) : document.getElementById(what)
if (crossobj.filters)
crossobj.filters.alpha.opacity=curpos
else if (crossobj.style.MozOpacity)
crossobj.style.MozOpacity=curpos/100
}

function startit(){
var crossobj=ie4? eval("document.all."+curcanvas) : document.getElementById(curcanvas)
crossobj.innerHTML='<img src="'+fadeimages[curimageindex]+'">'
rotateimage()
}

if (ie4||dom)
window.onload=startit
else
setInterval("rotateimage()",pause)
</script>

Hvad gør jeg forkert...?
