Thanks Charles, but actually that was the exact same article i was using when doing that numbering. From the beginning to the end. Maybe i missed something

You can end up with something that looks the same in all of Word's dialogs, but is not the same, if you break the sequence of steps. You need to establish all levels in one opening of the numbering dialog.

Thanks guys. I finally made it to work correctly, and the only source that helped me was this explanation: http://cybertext.wordpress.com/2010/...ist-numbering/ in case someone have the same problem
