Hello Everyone,

A while back Aditya provided a patch for using
*alternative=authornum* in *\cite*. The patch adds et al.
for the cases with more than two authors.
I have been using it without a hitch since then.

However, today I tried to use *extras* option with this patch
and it won't work. The MWE works for
*alternative=apa* and *alternative=num*

Please let me know if this can be rectified.

Regards,
Devendra

*MWE*
