Problem with Render Layers

untitled2.blend (700 KB)

I’m having a hard time working out what Render Layers are for and/or how they are used. I created a scene with a cube on Layer 1 and a sphere on Layer 2. I then created two render layers, and set one to render Scene layer 1 and the other to render Scene layer 2. However when I then selected my first render layer it also was now set to render scene layer 2. Whichever scene layer I set in one render layer was also reflected in the other. Am I doing something wrong? I’m trying to learn to use the compositor but these basic ideas seem to be eluding me.

Select both layers in the Scene layers and select the layer you want to render in the Layers.

Thanks! I was doing it the wrong way around.
