Conditional formatting a whole column but with the conditions < &

[Carolyn]

I am trying to get cells D2 thro' D71 to turn red if D65 cell formula is

63.0 and to turn yellow if D65 formula is <57.0

Formula in D65 is =D9/D10*D11*50
I have the following conditional formulas set up
Formula is =D$65>"63.0"
Formula is =D$65<"57.0"
But it will only turn yellow & seems to do this as soon as I enter data is
cell D9
Please help

Formula is =D$65>"63.0"

Formula is =D$65<"57.0"

Remove the quotes:

=D$65>63
=D$65<57

The second formula can be made more robust so that an empty cell won't be
formatted (if D65 might ever be empty):

=AND(COUNT(D$65),D$65<57)

An empty cell will evaluate to 0 and 0 < 57.
