Headers, footers and page numbers

I want to include ALL these in my document compiled draft.
at the moment, I can compile with either page numbers and a footer
OR trying to
edit and duplicate
use page settings

  • I can choose my headers and footers, but cannot find the way to include the page numbers
    does anyone know why/ what I am doing wrong?
    brief concise answers preferred, please.
    thank you anyone who can help/thinks they can
    kind regards
