Polskie t?umaczenie Polish translation

Hey k0rwi5, I was just about finishing putting your translation online but I found one problem.

Show %d hidden invitation code

Singular form:
Wy?wietl %d ukryty kod zaproszenia

Plural form (2):
Wy?wietl %d ukryte kody zaproszeń

But it also says there should be a unique pluralization for 5, can you tell me what that would be?

Don’t know if you find out the solution yourself, but just in case:
It’s a little bit more complicated.
For 1 you have:
Wy?wietl %d ukryty kod zaproszenia.
For 2-4 you have:
Wy?wietl %d ukryte kody zaproszenia.
For 5-21 you have:
Wy?wietl %d ukrytych kodów zaproszenia.
For 22-24 you have:
Wy?wietl %d ukryte kody zaproszenia.
For 25-31 you have:
Wy?wietl %d ukrytych kodów zaproszenia.
For 32-34 you have:
Wy?wietl %d ukryte kody zaproszenia.
For 35-41 you have:
Wy?wietl %d ukrytych kodów zaproszenia.
And it’s a loop.

Yuck, and this is why I’m glad I’m not a translator!
