Advanced display filter 2.0 - How does the Segment Number options work?

Question

I've tried the function Grouped Lists (spurred by Emma Goldsmith's tip "Use segment groups to display two separate sections of a file, similar to the MS Word Split Window feature"). So I've input various numbers in accordance with the examples given. I even tried to input exactly the numbers in the example. But I always get the same error message: input string has incorrect format, or in Swedish: 
 
 What am I doing wrong? I'm very curious as to the result of this filtering.
