Color other cells of the still to complete cells

Hi,

If there is a value in column A
Then empty cells in column B,C,D,E,F,G and I need to be colored red.
If Cell is filled in with value, color should become normal

See attached file for example

Hope this is possible
Thanks for the help

use a cf of =AND($A2<>"",B2="") in b2 apply to the other cells
