I guess I have not been too detailed with what I want. Here goes: there are various chapters numbered 1,2,3... For each chapter there are separate numberings like 0.1, 0.2...1.0,1.1...3.2.3.3...etc.



So the part in the number 2-1.0, has the 2 which is before the dash corresponding to the chapter number and the 1.0 after the dash corresponds to the details within the chapter. I'm able to implement the numbering as 1.01,1.02...1.10,1.11... but changing that initial digit to anything other than 1 seems to be a problem.

I hope this clarifies, thanks a lot for trying to help.
