Sumproduct produces #N/A

I have 1200 rows of data and I am trying to sum up the quantity of defects for month/year using SUMPRODUCT; works great. When I alter the formula to incorporate 25000 rows of data to prevent from manual editing down the road when we add additional data the result changes to #N/A

Is there another method to do, or something I am missing?

=SUMPRODUCT((I2=$I$2:$I$25000)*(MONTH(A2)=MONTH($A$2:$A$25000))*(YEAR(A2)=YEAR($A$2:$A$25000)))

Thank you so much.

Your SUMPRODUCT formula will then autoadjust to take into account the new data entered.

That said, what is the result of the data in column I? Is it text or numerical data? You may want to upload a sample workbook too.

Thanks for your reply, Column M and P are the SUMPRODUCT columns I want to extend to 25000 rows.

Are there any #N/A errors within any of the referenced ranges ?
You'ld have to eliminate those.

Thanks for your reply, I attached the workbook in my last post, I didn't seem to find any #N/A errors.

You have #N/A error values in column I (I552 I554 & I558)
Clear those errors and the sumproduct will be fine.

Of course I do My bad. Thank so much for everyone's help

You're welcome.

FYI, you can use the SpecialCells function to help find errors (much easier than looking for them with your eyes)
Highlight the range of cells and press CTRL + G, Click special
There are alot of options in there that can hlep you find certain types of cell values.
