Cond. Formatting; If Cell B6 or B7 is blank I want Cell D12 to be
I have a formula in Cell D12:
=SQRT(POWER($B$6,2)+POWER(B$7,2))
If in have no entry in Cell B6 or B7, I would like cell D12 to be blank.
I think it should be done with Conditional Formatting, but how do I identify
or recognize a blank (no entry) cell?
