Reply To: Doubling up page numbers

The next/previous page marker works if the two frames are linked together on the master. Helpful to know if you're ever working on a book with both page numbers on one page “002-003”.

Make a text box on each of the facing pages and link them together. On the left hand side, put the current page number, then a frame break, then the previous page number marker in the box on the right hand page. If you don't want exclusively even-numbered pages, you would then have to number your spreads by hand in the pages panel, and that's probably pretty easy with a script. You'd also need to turn off spread and page shuffling in the pages panel.
