Hi,

Can someone check this script? I can’t get a browser with resolution 480 x 480 and less (PDAs, Handhelds, etc…) to go to the url designated in var handheld.

```auto

			// Grab the screen resolution
			var width = screen.width;
			var height = screen.height;

			// Check the screen resolution
			var handheld = width <= 480 && height <= 480 ? true : false;

			// Change the following URLs to what you like
			var handheldURL = "http://www.pdaurl.com";
			var defaultURL = "http://www.screenurl.com";

			// Check and redirect
			var gotoURL = handheld ? handheldURL : defaultURL;

			if(document.images)
				{
				window.location.replace(gotoURL);
				}
				else
				{
				window.location = gotoURL;
				}

```
