Oh hi!

I cast aside my Indian films in order to help you with this! I use Open Office for just about everything.

The first thing you will want to do is go to Insert - Header or Footer (whichever one you want to use) and select All. There should be a Header or Footer on each page.

Then go to Insert - Fields - Page Number. Numbers should apply to the top or bottom of each page.

Should work. I tried it on my own computer several times, first. :D
