I am attempting to write a formula in a new sheet that sums the effort estimate for each individual by month.I feel like I'm very close as I no longer get an "unparseable" error, but my formula is returning a value of 0 when it should not. In the formula example below, I'm attempting to pull in the total of estimated hours for "Misty Lastname" for the month of January "1". Any help is appreciated!
=IFERROR(SUMIFS({Effort Estimated Column}, {Assigned To Column}, HAS({Assigned To Column}, "Misty Lastname"), {End Month Column}, "1"), "")
