Problems using @cell with dates when range contains blank cells

Eli Chuang

Hi,

I've been trying to use this formula:

COUNTIF(Due Date, MONTH(@cell) = 8, but it returns an error INVALID DATA TYPE

If I limit the data range to exclude the blank rows than it has no problems. But this is not pratical because later when I more tasks, I have to adjust the formula. Interestingly SUMIF does not have this problem using similar parameters.

Besides creating a new column to calculate the month separately any other solutions?

Try this instead:

=COUNTIF([Due Date]:[Due Date], IFERROR(MONTH(@cell), "") = 8)

This should let you skip the blank cells.
