Are you on Windows, Mac or both. You started a thread on a related question which you put in the MacOS forum:
I have given you an answer there, but on Compiling you can set either inspector or inline footnotes to be compiled as endnotes. I compile to RTF, and endnotes are compiled at the end of the document. I cannot believe that in Word it is impossible to change them to be placed at the end of sections, but as I say in the other thread, you’ll probably need to replace the page breaks before your chapters with “Section breaks next page” or whatever terminology Word uses.
