Problem with translating plural forms

[zaksmok]

Hello. I've got .po file created with poEdit with translated plural form (http://pastebin.com/6YvDx6gY).

Using translation function "echo ('dragon');" works fine but plural translations like "echo n('%s apple', '%s apples', 1);" or "echo n__('%s apple', '%s apples', 2);" gives "%s jabłko" and "%s jabłek".

So translation is good but dynamic value %s is not set,

I cannot figure out what I'm doing wrong. Can you help me?

Try with n__('%s apple', '%s apples', 2, 2);: does it work?

[zaksmok]

yes it works. But why i have to double $value?

[mlocati]

n__('%s apple', '%s apples', 2) gives you the correct plural translated string for 2 apples.
Further arguments (after the third), if specified, are used in a sprintf function to put these values to the translated string.
