A student just emailed me with this question.
In Word, if you choose the a, b, c, format for footnotes, if there are more than 26 footnotes, the footnotes are formatted as aa, bb, cc, etc.
But InDesign starts these additional footnotes as aa, ab, ac, ad, etc.
I've looked all over the help files, ID Secrets, and these forums and I can't find any way to fix the problem.
I finally had to resort to telling her to edit the PDF text (gasp!).
It's problably too late for her to fix this project, but anyone have any thoughts.
