Wolfgang,
Sorry, no guarantees on non English machines(Of course there are no guarantees on English machines either;-) ). Glad it's working on the English machine. I'm wondering if the hyperlink formula might be different on the German one. If you want to get it to work on that one, try typing in a =hyperlink() formula on it's excel version and see what happens. It may not be available.

I will be having the "Lots of beers" tonight.
:-)
