Hi
I am reading the primer at
http://www.shaunakelly.com/word/numb...Numbering.html
and I have done all that she says (starting even with a blank document
format) and I am setting my number levels.

She says: 3 Numbering for all lower levels.
For second and subsequent levels, indicate in the Previous Level Number box
whether you want to include the number from the previous level.

I am not entirely sure what she means here. I would think it would be
something to do with the numbering after 1.1.1 etc. By which I mean I would
have thought that it would control numbering when you get to a scheme like:

Chapter 1
1.1
1.1.1
1.1.2

Chapter 2
2.1
2.2
2.2.1
2.3
2.3.1
2.3.1.1

and so on.

But, if I try to make an entry in that space (let's say I am formatting
Level 5 and I pick Level 4 from that dropdown, then the Preview panel goes
nuts, and at level 5 I have something like 11.1.1..1 and the only way I can
override this again is by typing 1.1.1.1.1 in the Number Format field.

Can anyone enlighten me please?
Thanks
Phil
