sum if by month is returning #VALUE

[superboy]

In my worksheet, I recently started using this function =IF(A2<>"",TODAY(),"")
Basically whenever a value in A2 is entered. B2 gives me a date. I dragged down the function in my column so it can be automatic.
The problem now is, My excel function to calculate profit =SUM(IF(MONTH(B15:B9000)=A1,H15:H9000)) is returning a #VALUE
A1 is January aka 1 to represent the first month.

Any help on how to get around this issue will be greatly appreciated. Thank you.

When you apply MONTH function to a text value like "" you get #VALUE!

You can add another IF to the SUM to cut those out, i.e.

=SUM(IF(B15:B9000<>"",IF(MONTH(B15:B9000)=A1,H15:H9000)))

.......but if you use TODAY() in column B won't they always update to the current date, don't you want them to remain at the date when you entered the value?

Thank you. And yes that is so true, I did not think of that. How can I have it remain at the date when I entered the value?

You need a worksheet change event - something like this
