The page numbers in your book are automatically inserted at the bottom of each page.
So, to change the visible page number, do the following:
- place a new text box over the page number
- enter a new page number into the text box
- change the text box background color to dark gray to cover up the old page number.
For example, if you wanted page 16 to show "1" at the bottom of the page, you would create the following text box and put it on top of the "16".
