This returns the correct value for $width but falls down on the boolean. I have tried intval/srtval but nothing seems to work. Maybe it is too early! $width = " <script> document.write(screen.width); </script>"; //$ross= intval($width); echo $width; if ($width < 1064) { echo "lower"; $style= "style1.css"; } else { $style= "style2.css"; } R. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
