Look up formula needed for golf competition

Hi I am new to this and only recently joined the forum. I run Round Robin Competition where everybody plays everybody else once during the year. It gets harder to know who has played whom so far so I am looking for a chart that would show this and spread is attached with two tabs. One "Results" shows date played and outcome Tab two "Who played" shows all 32 players and I need the appropriate box to be filled in with date played ie "10/11/13" for game between Earl & Gale v Freestone & Moore.
Many thanks if this is possible
