Lets say I have a box that has a smaller box cut out of it, I.E. a room.
The room also has a window. But when I put a light in the room, it does
not show through the window. But it does seem to go through walls. What
is wrong? Could some one post some code for me to paste in?

Hope this helps

  Sorry, I don't understand what you mean.

You could try a media container the same size as the box that you used to
take the middle out of the room, or you could use a high ambient/diffuse value
on the window material.  I used ambient and diffuse on my trafficlights macro
to get that type of effect.  something like:

 object{GlassInWindow
             pigment{rgbf <1,0,0,0.85>}
             finish{ambient 5
                    diffuse 5
                    phong 0.8 
                    reflection 0.2
                    specular 0.01
                    roughness 0.001
                   }
             }
       
Not sure of the exact values I used, just play around with the diffuse and 
ambient values.

I don't quite get it. Where is the light source? That's what I'm really
looking for. And thanks for trying to help... doing this for fan art of an
online comic...
