"I myself put bottles of red wine on your tables."
Translation:Eu însumi pun sticle de vin roșu pe mesele voastre.
Tell me please, why ”Eu însumi pun sticle la vin roșu pe mesele tale” was not accepted as correct answer?
You cannot use the preposition "la" in this case. It doesn't make sense. It sounds like, instead of "bottles of red wine", you are saying "bottles at red wine". Again, it doesn't make sense.
