As Thorstein already has located the error,
I will not comment on that.


I do not know what you are really doing
with your loops.

But if you are doing what I think you are
(placing objects in a 3D grid), then I have
a little suggestion for you below.

If I'm guessing wrong, then please disregard
this post.


Best regards,
