Is it possible to create a countifs statement like the following: =COUNTIFS([% Complete]:[% Complete], =1, [Project Finish]:[Project Finish],AND(IFERROR((YEAR(@cell), 0) = 2018),IFERROR((MONTH(@cell), 0) = 2)) ? I am trying the following equation to search for 100% complete and during a specified month and year. I am getting a #unparseable error when tying the equation. I have success with a similar equation: =COUNTIFS([% Complete]:[% Complete], =1, [Project Finish]:[Project Finish], IFERROR(YEAR(@cell), 0) = 2017)
