Hello,
I'm reporting the issue here, because it's related to fmtcountpackage, the correction will probably be handled by @nlct, because the problem is on the Dickimaw Books website.
On page: https://www.dickimaw-books.com/faq.php?itemlabel=frenchdialects :
septente should be written septante (with an A).
- the option value for French from Belgium is
belgian, indeed, and not belgium.
The documentation provided in the package on CTAN is correct for both items.
Thanks!
