Why Won't Edited Cells Change?

Hello. I have massive problem that make me stomp myself angry.

I am very familiar with building epm REPORT. Yes. My only problem is that my change function not working at all. I have done this lots of times beyond 20. I want cells that user changes like from 200 to 300, to change color (YELLOW), so they and see no question.

I make changes on formatting sheet like i have many times. I hit refresh and I get very crazy because it does not work.

See HERE. Please help. I will thanks and thumbs up.
