Hello,
I tried to use the workflow with my own data.

There is a row filter, named "remove authors with only one pub"

there is a warning : String comparison is used for range checking.

Any help ? Has anyone expierence with this example.

Thanks in advance to the author and thanks for any help

Sorry, correct myself.

Now used another dataset, containing different Journals, the first query was concerning one specific Journal. 
Now everthing works fine.

Thanks to Frank Dullweber for his great work. Really interesting to see, who is publishing in a certain domain.
