what is transaction ids? my bitcoin adresse?
No, when you send or receive bitcoins that transaction has an ID associated with it. We use that to index all payments so we need that to identify what is happening if you think there is a problem.
7 off 8 transactions I made shows as paid on the website, I've only recieved 3 off them.
