Re: Sidefootnote

Avevo già provato nella forma

\renewcommand*{\sidefootform}{\rightskip=\z@ \@plus 2em}

con e senza asterisco ma ottengo il messaggio:

The control sequence at the end of the top line
of your error message was never \def’ed. If you have
misspelled it (e.g., `\hobx’), type `I’ and the correct
spelling (e.g., `I\hbox’). Otherwise just continue,
and I’ll forget about whatever was undefined.
