Ok, you got my respect for that. When I think about it, I think you're right. And now I even don't dare to say more, not even ask another question ( 😉 ). I feel really stupid. I saw the solution. But (as we say in Norway in Norwegian of course) I just had to shit on my own leg. I feel so embarrassed. Before I was never afraid to try new things or find solutions. It must be my age. I am getting older and the Alzheimer's is closing up on me. Requinix, SORRY FOR ASKING STUPID SELF EXPLAINED QUESTIONS. But, thank you for listening
