I'm glad because you found an aswer and I'm sad because I couldn't help as much as possible!
I wonder why nobody answered to your question, I think it's not so difficult.

Thanks a lot, Antonia! I have found an answer!

I know a little German, and I wrote these notes only for helping others, because I saw that nobody wants to post an answer.
