Feinripp, Vampire, thank you both very much for helping me. I will give it a go. I use UP 2.1. And I'm sure it is me who has done something wrong. I will let you know the outcome.

Btw, I can understand German perfectly well, but writing is somewhat weaker, so I prefer to answer in English. You can comment in German though, no problem. Thanks again for your help.
