I am trying to do a CF on a cell as follows:

If D40 is not blank and E40 is blank, I would like to apply the CF.
D40 and E40 are both formatted as dates.

I tried =AND(D40<"",E40=""), but it did not work.
I also tried comparing it to 0 (zero) rather than to "", but it still
didn't
work.

Any ideas?
