Auto fill column based on adjacent column

Hello,

I'm trying to write a macro to do the following:

- In a sheet, auto fill the column "Adjusted" with the values in the column "PM"
- Only auto populate the column of the active sheet, as this is a shared workbook. I do not want to overwrite other people's work.

Is this possible? I've attached my workbook with the six tabs. I have not been able to figure this out. Thanks for any help!
