NADA, NO LO CONSIGO SOLUCIONAR:
Si alguien sabe como o ve una manera mas sencilla de hacer lo mismo, que me diga como.
El codigo lo que pretende es ver la resolucion de la pantalla del visitante y en base a eso mostrar un swf con esas dimensiones.
<html>
<head>
<% if Request.Querystring("resolucion")="" then%>
<script>
var ancho,alto, url
if ((screen.width == 800) && (screen.height == 600)){
ancho="800"
alto="600";
url="default.asp?resolucion=1"}
else if ((screen.width == 1024) && (screen.height == 768)){
ancho="1024"
alto="768";
