Dear All, I have a page in php which I wanted to have centered in all resolutions. I have used a script which I fouund on the Internet called get_resolution.php. It uses javascript to determine the client resolution and puts it in a cookie, then php will red the cookie and puts it in a variable which I can use to calculate the left and right margin. It works perfect, but somtimes and on some machines I get the blanco page of get_resolution, Any one any idear why this happens?
