Javascript is client side and will only run in the browser, you cannot run it from the server inside cfml.
so <cfset session.screenwidth = "<script>document.write( screen.width);</script>"> will simply assign the text "<script>document.write(screen.width);</script>" to session.screenwidth not the value your are expecting. you need to run this script client side. <script>document.write(screen.width);</script> and then send the values back to the server, you could do this with ajax or cookies.
