Brick texture using node editor. Blend included

I have no idea what I’m doing wrong.
I used the node editor,made a color,bump,
and spec map.
But it seems like the nor and spec isn’t working.
I’d like to know what I’m doing wrong,so I attached the blend.
I’ve got the textures i made linked up to the material but it isn’t working for some reason.

Not sure about the spec but normal will work if you move the input from “color” to “normal” in the normal’s output node.
