Hallo Wolfgang!

This works.
How do you find your peaces of wisdom?

But I have not understand the whole figurenumber thing.

It is obviously (my example shows this), that there must
be a hidden number.

What is its name?
How can this number be influenzed?
What is 'checked' or 'not checked' in the above option?
And why does this produce the effect I wanted?

Gruß, Wolfgang
