You are welcome, glad it helps a bit!

Hi - if you want people to help you please post in English in Discourse; most people are using it as 2nd language and it's not difficult to use automatic translator to ask simple questions.

To answer your question - please see this earlier detailled comment (you can try to autotranslate it, if that helps you better), while you wait for native speaker to reply otherwise.
