Do you have alternate layouts or complicated page numbering? If so, then the warning dialog seems to carry enough instruction in the message it bears.
I don't know those functions "alternate layouts or complicated page", I just added to page number marker to all master pages.
When I tried once, the most I could do was two sets of pages. Don't know if it is a limitation.
What version of InDesign are you using? Do you have more than one "section" in document (set up with Numbering and Section options) and do any page numbers repeat?
I'm using the CS6 on Windows 7. I'm not sure about the "sections", I just have 3 different master pages with page number marker, that's all. Every page is different, excluding a few blank pages.
In the prefs, General section, what is set in the top dropdown for PageNumbering: View? If it isn't set to Section Numbering, set it to that and check again in the pages panel for duplicate numbers.
It's set on "Section Numbering".
I would be nice to receive direct the right input for "Pages - Range:" under the PDF Export for my specific case. A concrete example would be better than thousand words.
The only thing I can think of that would cause your error (and I tried a similar export 2 days ago to check) is if there are duplicate page numbers or alternate layouts (that you might not be showing as alternates in the panel).
I still don't know what to do
Are you able to export other ranges from this file? ranges from other files? Could be a problem with the file, or with your program or configuration.
I can't tell you exactly what is wrong, only that the error is not "normal" behavior.
Yes, I can export other ranges from this file, I have tried right now "14-15,18-20" and I works fine. I have tried even the combination "1-7,22,23,43,46,47,52,53" and it works!
I don't know why before it didn't worked, but not it's fine!
@Matt – I'd try the following method for getting the "absolute" numbers of the pages:
A. This will work in CS5.5 and below:
B. This will not work in CS6 (maybe a bug?)
C. This will work in CS6:
Of course only, if your document begins with page 1 in numbering.
Now for the reasons for getting this alternate layout message:
You did not use this method, but it should be mentioned here:
1. If you are using method A or B from above the range cannot be detected in CS6. This seems to be a bug.
2. If you are moving or duplicating pages from a different document to a document in CS6 and above a new alternate layout will be created automatically sometimes
If you are using the default settings of the Pages Panel, these alternate layouts cannot be seen.
You can make them visible by checking the options from the Pages Panel.
