Setting the language for an app store link?

Question

Here's an example of a URL (random selection):

http://itunes.apple.com/ca/app/imdb-movies-tv/id342792525?mt=8

Now here's the same link in French:

http://itunes.apple.com/fr/app/imdb-movies-tv/id342792525?mt=8

Note that I changed the country code in the URL from "ca" to "fr". Seems to work fine for this app. However, I'm unable to get it working for my application.

I've added "Canadian French" as an additional language - is this the reason? Should it be "French" instead? I do not wish the app to be sold in the France App Store, but I do want the localization for Canadian-French users.

Thanks!

EDIT: Bumping.
