Okay, I'm stumped again. Your code example was very clear but I'm still confused on how to get artlayer object itself.
I'm coding this script for a client that works in construction. They want a .PSD file that they can show a variety of building options to their customers. (Siding colors, roofing styles etc.)
My script is to make only one option(layer) visible at one time. For example, if my client clicks on roofing style #2, then my script would hide roofing style #1.
If I could just get the object reference of the art layer, I would be good to go.
