Deliverable Futures for Gold.


I am new with futures and want to have some clarifications. As I understood, in deliverable future for gold should be fixed price for expiration date, that is in contract clear has been set by seller. But in real, I never find this price in the contract. The only price that can be seen is the current gold market price for deliverable futures. And this price has no difference with actual gold price.

I thought that the deliverable future is the contract between seller A that promise to deliver gold at fixed price at the expiration day. Am I wrong? If not where to see this price?
