Some commands and data tags dont work

I was trying to make a house for my brother but I wanted to make it fancy, so I added command blocks and redstone. But when I tryed to ude the command blocks I got errors.

What I expected to happen was...:
It would follow out the command

What actually happened was...:
It brought up tons of errors

Steps to Reproduce:
Try to use the fill command, and modifiers on the testfor command
