Asking for clarifying

Could you speak a little more specific?

Could you explain the problem in more detail?

I am not sure I understand. Could you explain it to me again?

OK let me see if I understand you.

One question Johnathan. You mentioned the go-live on the 25th. Could you explain what you need from us to make sure everything goes smoothly?

OK John. I just want to make sure that I understand your problem.

Is that correct?
