STUMPER- changing screen width in slideshow

I'm using a modified version of dynamic drive's slideshow, but it uses a fixed width which is very annoying. I wanted to change it to utilize the screen width, but it doesn't seem to work. I tried using a var sw=screen.width and subbed out the variable, tried subbing it out on the write.ln, but that didn't work either.

<script type="text/javascript">

//Specify the slider's width (in pixels)
var sliderwidth="982px"
//Specify the slider's height
var sliderheight="263px"
//Specify the slider's slide speed (larger is faster 1-10)
var slidespeed=1
//configure background color:
slidebgcolor="#000000"

//Specify the slider's images
var leftrightslide=new Array()
var finalslide=''


leftrightslide[0]='<a href="#"><img src="test/1j.jpg" border=0></a>'
leftrightslide[1]='<a href="#"><img src="test/1b.jpg" border=0></a>'

</script>

If anyone can help I'd appreciate it.
Thanks!

Wow, that is some ugly code. Checking for document.layers? That's ancient. Using document.write... I would probably suggest scrapping this and finding a more current slideshow.

Unfortunately I have tried. I realize it's antiquated code, but most sliding images are the 'show image, show next image, click to see larger image' type of function and I'm looking for this kind of functionality.

Any further thoughts?

I got the answer. If anyone else is in my boat, then here is the updated code:
[dynamicdrive.com...]
It supports width:100%

Thanks All!
