Testing out a green screen layer..after applying chroma and spill applied displacement and layer turned completely black. Am I missing a step?

What are you using for the background track underneath the green screen layer?

When you apply displacement to a layer, it uses the color data from that layer to displace the colors in the layer below it. So, when you apply displacement to an actor filmed in front of a greenscreen, for example, the background behind him will be displaced based on the color data of the greenscreened actor, and the actual greenscreen layer will be invisible.

So the question is, do you not have a background behind the greenscreen layer, or is it turning black on top of your background?

Cool. Displacement effects can be a bit tricky to get the hang of at first, but I'm sure you'll get it down soon. Hopefully understanding how it actually works will help with figuring out how to set up the layers correctly.

Try this, it's super duper basic and is very simple and easy to understand. Hope it helps.
