How to make translation work?

I have made a partiel translation of en-GB.php file, and saved it as da-dk.php.

The default language of my joomlainstallation is danish. I uploadede the da-dk.php file in the folder Joomshopping / lang - along with the german, english and russian languagefiles.

But how do I choose the da-DK file / language?!

Joomshopping is very easy to use, but this one I can't figure out :(
