Thanks that works.

Because the cell is not empty. Having no value is not
the same.

You could try

=SUMPRODUCT(--(LEN($F$99:F100)0))

Hi

I have these formulas in the following cells,

F100 (=IF(ISBLANK('New Conference Office Sheet'!
B24),"",'New Conference Office Sheet'!B24))

T100 (=COUNTIF($F$99:F100,"<"""))


Why is the Countif function including F100 in the count
when it returns a value of "" ?

Thanks.
