To add a section after the endnotes, you have to set endnote location to end of section. Then you use the "Suppress endnotes" option (in the Page Setup dialog box) for the appropriate sections to "postpone" their display so that the display at the end of the next-to-last section. Trust me, this does work—at least it does in WinWord.

"Endnote text" is the text typed into an individual endnote. Again, I don't know how right-clicking to bring up the context menu works in MacWord, but you seem to have found the Footnote and Endnote dialog box anyway, so it doesn't matter.

Have you been able to locate the Page Setup dialog box?
