Setting different Headers and Footers on odd and even pages in Pages
I am trying to lay out a book that has a different header on even and odd pages (and no header at the start of a new chapter) but all the posts I have found talk of options that don't seem to appear on my system (Mac Mini, Pages 13.2). Also, the page number is at the bottom of the first page of a new chapter and at the top right of other pages.
I cannot find how to set these up and below are grabs of the options that appear for me. All I can see is how to not show both the header and footer on the first page of a section.
The original book I wrote was done in Word Perfect 4.2 (shows how long ago that was) and it was straightforward to do these things.
Please advise.
Thank you
