Working with multi-dimension arrays - help please.

Hi, if I have a object that includes a multi dimensional array:

sport = new Object();

sport.game = new Array(1);
sport.game[0] = new Array(2);
sport.game[0][1] = 12;
sport.game[0][2] = 24;

sport.game[1] = new Array(2);
sport.game[1][1] = 3;
sport.game[1][2] = 7;

a1 = sport.game [0][2];  // Is there a way to get the value [0] highlighted in yellow,
a1 = sport.game [1][2];  // Or in the second case the value [1] highlighted in yellow?

Thanks in advance.
