I am trying to make a spreadsheet black out non-needed information for individuals that meet a certain criteria. Their criteria is in column `A`

and I need it to void cells `B10:15`

through `C10:15`

and cells `F10:15`

through `J10:15`

To sum up: if cell `A10`

is less than or equal to X then color in black cells `B10:15`

through `C10:15`

and cells `F10:15`

through `J10:15`

.
