Neon Light Corridor issues

Zwyt

There is a problem with Neon Light Corridor that I have run into, whenever I apply one of the colored light shaders to the corridor I just get this white square/rectangle that blocks the view of the corridor, it appears to be the surface that makes up the walls of the corridor itself. Not sure what is going on unless the front needs to be made transparent but I am not sure I can do this without making all of the walls transparent. Note: This only happens when in iRay preview or in the actual render.

Never mind I discovered that the shaders should not be applied to the surface of the wall but to the light blue, light pink, and light purple surfaces of the light railings inside of the wall. Typical shader confusion. :)
