I decided to build this in creative mode first. It spawns mobs very well, but I'm having trouble with the redstone.

At some point in the video, he says to wire up one side just like the other and the video then cuts away. I did that, but it did not work. Upon closer inspection of the video, it is actually different, and I think it might have escaped his mind. I tried to mimic exactly what he did, but I could not make one of the sides work. I'm not very redstone savvy, so I'm having a lot of difficulty understanding. Any pointers?

He starts building the side I'm having difficulty with at 20:51.
