Bob,

that's exactly what I need, excellent!

It's necessary becaues I exclude Machine 3 and 4 because they are
other types of machines
and in later years (it's a dataseries, which starts in the year 1999)
they have numbers.
So I have to exclude them also when they have numbers.

Best Regards
Werner
