Other than manually using the interactive features to check a page number on the last page, not as far as I know.
Thank you for the feedback. Could you elaborate on "interactive features."
You can optimize a container field for interactive content so that you can scroll through all pages of your PDF. If the pages of the PDF include page numbers, you can go to the last page and check the page number--not what you wanted to hear, but that's the only method that I can think of.
Since I'm running on a Mac Pro (10.7.5) would it be possible, using an AppleScript, to export the PDF, open the PDF, capture, the number of pages, and then pass that information back to FileMaker?
Anyone with experience around that?
I don't own a mac and haven't touched an AppleScript in years, but if AppleScript can determine the page count, it can definitely put that value into a field in FileMaker.
The Applescript is a possible way. Word or most have a page counter, so does your print driver.
You probably have to do a visual count then enter that in a new field of you container record, which is what Phil is suggesting.
Remember page count depends on page size defined when you printed to the PDF file.
