@ I Load an Action, then run action. I get a box that pops up on each layer that says this command unavailable. How do I make each layer available?
We can't know. We do not know anything about what steps your action contains, your documents, your version of PS, your system. You have to provide much more details before anyone can even begin to guess.
I figured out my problem. I am using photoshop CS6 On a Mac. When loading an action have a picture open, and the action will Run properly. I was loading and running action without a picture open (black screen).
