I'm developing a book in FrameMaker, and I have an insert to put in between pages 12 and 13. The page numbers of the insert are 12A and 12B, and then I want the document to resume numbering at 13. Currently I am using the pagenum feature from Insert>Headers & Footers>Page Number. However, after pages 12A and 12B, the page number feature numbers the next page as page 15.... how do I get it to resume counting at 13?
Right click page 15 > Numbering & Section Options and then set Start Page Numbering to 13.
If the page inserts are in separate files and you are adding these to the book, then Barb's suggestion is the way to go. However, if these inserts are in an existing file, then FM will just keep track of the actual pages present. There is an old feature that has been deprecated (but still present) called Freeze Pagination explicitly for this purpose. However, it was quirky and converts the document to a series of disconnected pages. You could try it on a copy of your file to see how it works for you. It is triggered by a keyboard shortcut: esc p z.

Dog gone it. I thought this question was in the InDesign forum and gave an InDesign answer. (I'm still at the Creative Cloud conference where I'm totally immersed in the CC apps).
Please disregard my earlier answer. Point pages as described by Arnis are your best bet.
