[SOLVED] Noob formating help

Sorry for very noob question.
I want my novel to be have short pieces of text with number headings:

1. Once upon a time... 2. This is second part... 3. This is third part, etc

So, no special chapter or sub-chapter headings, no announcement, no new page.

I try to format these pieces as chapter, but after compiling I receive

CHAPTER ONE 1. Once upon a time...

Any formating tips, please?
