webiopiの質問です

webiopiを使って、ブラウザに複数のボタンを表示させ、ラズベリーパイの複数のGPIOをon,offしたいのですが、うまくいきません。
具体的にはGPIO12,13をそれぞれブラウザのボタンでON,OFFしたいのですが。
下記のようにプログラムを作成すると、ブラウザが「このサイトにアクセスできません」と表示されます。script.pyの7行目「LIGHT2 = 13」と14行目「GPIO.setFunction(LIGHT2, GPIO.OUT)」と最終行「GPIO.digitalWrite(LIGHT2, GPIO.LOW)」を消すと、ブラウザはアクセスできて、GPIO12だけ操作できます。
GPIO13も操作できるようにするにはどうしたらいいでしょうか？
宜しくお願い致します。
