When stuff like this happens use
var_dump($_POST);
to see what is happening.
The behavior is different in IE and FF and probaby others too.
In IE it posts the location of the mouse click as lang_x and lang_y which
leaves $_POST['lang'] emptier than you'd like. OTOH if you do
$lang=$_POST['lang_x']; you'll find the x loc of the mouse click in $lang
In FF it posts the x and y coords and a 'lang' value so your code actually
works in FF but not IE.
It seems that neither browser conforms to HTML4 which seems to use a
lang.x and lang.y form here
http://www.w3.org/TR/html4/interact/forms.html#h-17.4.1
and that's what they show in here also
http://www.htmlhelp.com/reference/html40/forms/input.html
but sadly the browsers do what they do.
