Thank you! That works fine.
First I want to get a template, that makes a initial form from a series:
Title: The Two Towers
Series: The Lord of the Rings
SeriesNumber: 2
This should give:
The Two Towers - TLotR [2]
But after some time on
this site I saw that this is not as easy as only add the series number.
Thanks and best regards
Dirk
