Thank you Mark, It worked finnaly the way you described.
However, this Plural thing doesn’t work the same way in all languages. For instance, in Arabic, there is a singular (for 1) called mofrad, a special plural called mothanna (for 2), another plural (from 3 till 10) and anoth plural (from 11 and up).
For instance, 1 user → مستخدم
2 users → مستخدمان/ مستخدمَيْن
3-10 users → مستخدمِين / مستخدمون
> 10 users → مستخدم
and to make it more complicated, we take into consideration only the last two (least significat) digits.
