Hi Brian, create the point object by going to Draw curve / More / Point.

The point should be placed at the spot that you want the scaling to happen from, select the point along with your objects when you array them.

See here: http://moi3d.com/forum/index.php?webtag=MOI&msg=275.109
for the original ScaleArray post that has some more details and an example image.

Let me know if you are still stuck.
