Zweihundertfünfzehn
I'm not trying to correct you to be annoying, Guitar_Girl, but whenever you write in German and forget the umlaut where an umlaut is needed, the word isn't... the word. The letter with an umlaut is there for a reason. I mean, you can technically write "zwolf" or "Madchen" and most people will know what you're talking about, but "zwölf" and "Mädchen" are far more preferred (seeing as they are the correct form).
