Displaying logical page numbers

It is not appearing where?

If you have renumbered the pages through "Page" view panel, the renumbered value will appear in the "Page Navigation" tool bar's Page Number window and on certain UI windows like the "Print".

"Logical Page Number" is not the same as Acrobat's JavaScript zero based page number.

That's what I can't figure out how to do: renumber the pages.

Open the Navigation Panel. Click on the "Pages" or "Thumbnail" display. Right click on a page and bring up the context sensitive menu. Select the "Number Pages" option. Complete the options as needed to add the logical numbering options you want to apply to the selected pages.
