You know what you need? More coffee. Your brain
is not activated yet this morning! I would guess
the y value you are looking for is also in the 7th
row. If fact, the z value that goes with that x value
is *also* in the 7th row! :-)

x = array[0,7]
y = array[1,7]
z = array[2,7]

But, even when you get this sorted out, your troubles
are only beginning. I think you are going to have to
re-think (get a LOT of coffee!!) your original premise
on how to attached these points together. It's a lot
harder to do this correctly than you imagine. :-)

Cheers,

David
