I assume, you selected the language "Persian" in SoSci Survey ("per"), is that correct? Is that always Farsi? I must admit that my knowledge about languages is quite limited and if "Farsi" was the better label, then we shouldchange that.
Regarding the numbers: How does numbering in Farsi work? Is it a traditional decimal system and only the numbers are different (than I would just need the numbers 0 to 10, please) or is it more complex?
