3w-1-3w-1-2 is a legal formation.
3n-1-3w-1-2 or 3w-1-3n-1-2 are both legal too.
3n-1-3n-1-2 would be illegal.
I hope that answers your question. Although I'm not even sure if you are asking a question because your translator is garbage. The mods might get mad, but I'd suggest posting both the translation and your native language.
