Have you set the data like that or is an import? You could achieve this more efficiently by using a PivotTable if the data was arranged correctly.

HI Roy, I wish I could use a pivot but the original data set is not in the correct form. What I uploaded was pieces from the original. I would like to be able to sum per month and reference the data from the other sheet. I would like to reference data from teh other sheet to avoid the summary sheet having too much information.

I thought that must be the case. Is there no way to re-format the data? Maybe, just copy and pastespecial - transpose.
I've just tried and the SUMIFS works fine on the same sheet, but not with the other sheet. I'll try to find out why.

I just tried too and I think the range and the sum range need to be on the same sheet. The month you are referring to (criteria) for the sum can be on the sheet with the formula.
This is really strange. It works perfectly when the data is arranged vertically. Note I changed the criteria to an actual date and formatted it "mmmm" on the Data Test Sheet, I prefere when working with dates to actually use real dates. EE-SumIF-Dates--1-.xlsx
