[users] Numbering level in Styles

[Josemar Müller Lohn]

Hello all:

I need to vinculate a style to a numbering level in OO 2.4.1. I found a way
to number them but all appears to be in the same level then I have to change
it manually.
I need this result:

1. Style Title 1
1.1. Style Title 2

But I can only get this automatically:

1. Style Title 1
2. Style Title 2

Thanks all...

Josemar
