PHP : switch

Hey guy. Im learning php, it seriously kicks…

I’m having a problem witht he switch() function though. It’s like it’s not recognizing the ‘default’ case. this is what i have…

$x = $_GET[‘x’];
switch($x) {
case 1:
echo “1”;
break;
case 2:
echo “2”;
break;
case 3:
echo “3”;
break;
default:
echo “default”;
}

but it gives me this error…

Notice: Undefined index: x in c:\Inetpub\wwwroot\adcore emp_site.php on line 10
default

line 10 being ->$x = $_GET[‘x’];

anyone? thank,
