    hi, Stuznet

         You can try to use this formula

    AprilStartPlan =
SWITCH (
    TRUE (),
    MAX ( DateTable[month] ) = "April", CALCULATE (
        COUNT ( Data[ID] ),
        FILTER (
            Data,
            [Plan Month] = "Apr"
                && [Plan Year] = "2018"
                && [SavedDate] = "March"
        )
    ),
    MAX ( DateTable[month] ) = "March", CALCULATE (
        COUNT ( Data[ID] ),
        FILTER (
            Data,
            [Plan Month] = "Mar"
                && [Plan Year] = "2018"
                && [SavedDate] = "March"
        )
    )
)

    Result:

    here is pbix, please try it.

    By the way, your error that one ) is missing, there should be two ")" in this.

     

    Best Regards,

Sooo, is there a pattern to that at all? If not, you could use a SWITCH TRUE statement like:

 

Measure = 
SWITCH(
  TRUE(),
  MAX([Month]) = "April", CALCULATE(COUNT([ID]),FILTER('Table',[Plan Month]="April" && [Plan Year] = 2018 && [SavedDate]="March"),
  MAX([Month]) = "May", CALCULATE(COUNT([ID]),FILTER('Table',[Plan Month]="May" && [Plan Year] = 2018 && [SavedDate]="April"),
)

Greg_Decklerthank you for helping me. I used your provided solution but I'm getting an error 

 

A function 'MAX' has been used in a True/False expression that is used as a table filter expression. This is not allowed.

AprilStartPlan = SWITCH(TRUE(),
    MAX('DateTable[month])="April", CALCULATE(COUNT(Data[ID]),
        FILTER(Data,[Plan Month] = "April" &&
            [Plan Year] = "2018" &&
            [SavedDate] = "March"),
    MAX(DateTable[month]) = "May", CALCULATE(COUNT(Data[ID]),
        FILTER(Data,[Plan Month] = "May" &&
            [Plan Year] = "2018" &&
            [SavedDate] = "April"))))
