I want to lock cells G7 (compensation), H7 (Hire), I7 (rectification), J7 (AD), K7 (other). the bracets are the title of the column.

In F7 i have a dropdown list with a choice of: compensation, hire, rectification, AD, other and combination.

I want G7 (compensation) to unlock (and or change colour) if i choose compensation from my drop down in F7, H7 to unlock if i choose hire, and so on. If i choose combination in F7 i want G7,H7,I7,J7 and K7 to unlock (and or change colour).

i hope this makes sence, and is possible. any questions let me know
