I'm experiencing an issue similar to this one:
I have a paragraph in which I reference a dollar amount (preceded by "$"). Attempting to insert a footnote anywhere in that paragraph gets me the error "Cannot insert a footnote here." Inserting one manually leaves the text black vs. fontified in the typical link color. Export produces it as the verbatim text ([fn:xx]) instead of converting it. Trying to escape the $ sign with \ doesn't fix the issue. Inserting another $ re-activates the footnote, but that will obviously convert my dollar amount to math font, which isn't what I want.
Any suggestions?
Thanks,
John
