Hi,

I need your help please. I have a need to calculate a sum of numbers in one
range if criteria are met from two other ranges. I have this formula that
calculates the correct sum for one critera, =SUMIF(B12:B399,"=PI",E12:E399),
now I need to add the second criteria. The second range is a date format. I
need my result to be monthly sums where the data in the second criteria range
are days entered in date format from all twelve months.
