This worked very well, thanks. I now want at the end of each chapter some
questions with the chapter number in the follow-up number, and then at the
end of the document a separate chapter with the answers with matching
numbers. In general for a single QA section this works, but now I start
distributing it over a number of chapters, the question and answer
numbering seems to be an issue. Would the define require a change?

I have it working with a single chapter:
