Swap item position in vector / array???

[itsallgood]

Hi all,

Can anyone explain how I swap the data in gameGrid[1] to gameGrid[2] (and the data in 2 goes into 1).

var gameGrid:Vector.<Vector.<int>> = new Vector.<Vector.<int>>();

gameGrid[0] = new Vector.<int>();
gameGrid[0][0] = 1;
gameGrid[0][1] = 2;
gameGrid[0][2] = 3;

gameGrid[1] = new Vector.<int>();
gameGrid[1][0] = 5;
gameGrid[1][1] = 6;
gameGrid[1][2] = 7;

gameGrid[2] = new Vector.<int>();
gameGrid[2][0] = 12;
gameGrid[2][1] = 13;
gameGrid[2][2] = 14;


// I imagine the data is being stored like this... [[1,2,3],[5,6,7],[12,13,14]]

trace(gameGrid[1][1]) // 6


How do i swap the data in gameGrid[1] to gameGrid[2]

Thanks for the help!
