I still cannot Birail these curves, can someone help me with why it refuses to work?

I'm sure all of my points are either connected to another curves end point, or is connected to the middle of a curve. I've done snap to point and snap to curve and made sure they are all correct.

Below are my curves, I highlighted each one in a different color. (See my previous post for a non-highlighted version) Is there any reason this would not work?

I figured the red curve might be the problem since it is not only on the top, but on the left side of the birail-to-be. so I detached it near where the light would be, and snapped the points, but it still wouldn't work.

Please help!

EDIT: Ok, I hid everything in my scene except the curves I needed, then took out my hammer and bashed it to death for a while, and viola! It birailed! Basically what was wrong was the red curve needed to be detached, the green curve was not snapped to the pink curve (but was so very very close), and the red and cyan curves were like 0.01 units apart. I have no idea how all those things were messed up when I had jsut check them several times over... OH well, it's all working now. I'll have an update with a screenshot probably tomarrow, since it is quite late tonight to get much done, besides tweaking the birailed surface a little.
