[SOLVED] Help locking particle emission to alpha channel?

My project file is here. If you need the mp4 it is here

I have a layer which is originally just black with green blocks falling down. I would like the particles to emit from the green blocks, so I try keying out the black background. Then when I lock the particles to that layer and emit from alpha, it fails to emit from the green blocks. It just emits from the entire image.

I've been working on this all night watching all the videos, can someone please tell me what I'm doing wrong?
