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

=IF(ISERROR(MATCH(SUBSTITUTE($A2&B$1," ",""),SUBSTITUTE(results!$E$2:$E$13&results!$I$2:$I$13," ",""),0)),"","X")&IF(ISERROR(MATCH(SUBSTITUTE($A2&B$1," ",""),SUBSTITUTE(results!$I$2:$I$13&results!$E$2:$E$13," ",""),0)),"","X")

In B2 and copies across down, it's an array formula so needs to be confirmed with Ctrl+shift+enter. It is spelling/case sensitive.

Many thanks XOR LX for your reply and I entered the formula exactly as given and after changing the names and spelling so as they matched all appears OK and many thanks. I also used the other reply sent which worked very well so I have solved my current problem and no doubt will be asking more questions after receiving such great replies that worked. Many thanks again
