I can only second what Glenn said .. begin with the Array of Arrays method (and maybe just stick to it)

The real Multidimensional Array [x,y] is a bit awkward to use. One thing comes to mind:
They may support up to 60 dimensions but if you redim and preserve the array you can only alter the 'rightmost' dimension (y)

As soon as you understood how [x][y] works you will love it..
