Hi Andy,

Check all the ranges involved just in case they already contain the VALUE
error.
Check the ranges [Log!$A$2:$A$200] and [Stats!$D1] - potentially one of them
or both contain values that appear as dates, but are in reality text
strings.

Regards,

Using the below formula, #VALUE! is returned:

=SUMPRODUCT(--(MONTH(Log!$A$2:$A$200)=MONTH(Stats!$D1)),--(Log!$D$2:$D$200=(Stats!$A3)))

I think it is because Log! is linked to a 3rd sheet and contains
ISBLANK as below:

=IF(ISBLANK(Benefit_Plan_Review_Log.csv!$N2),"",Be nefit_Plan_Review_Log.csv!$N2)

Is there anything I can do?

Many thanks

Andy
