Hi Zygmunt! Thank you so much for your help! And sorry for replying late, I didn't mean to.
I guess I need to do my forum-settings different ?, so I get notice when someone replies.
Aha, I see I will change what you recomended in the coding. and you´ve helped me to understand what the codes stands for. thanks.
sure I will "upvote" you - how do I do so?
best wishes,
Franziska
