Thank you dillidüdük. But i can still be wrong.Do you think when means "what time" or " at the time" in this sentence. My idea is we need a question mark to know at the end of the sentence to know what it means exactly. Do you agree? If there was a question mark at the end, i could translate it as "Bana varacağın zamanı bildirir misin?"

Sorry for explaining that wrong and the sentence in Turkish was totally correct I agree.

But like Gokuyum said we have to know what Sam meant exactly before we can know which translation to use now.

No problem Melike. We really need to know what he meant. But a question mark could be helpful
