DAX Error SUMX

Hi,

I am not sure how your semantic model looks like, but please try something like below whether it suits your inquiry.

SUMX (
    VALUES ( 'Calendar'[Calendar] ),
    IF (
        NOT ( ISBLANK ( [Wages on Flat Units] ) ),
        CALCULATE (
            SUM ( 'WagesHomeCC and Fringe Line Items'[Amount] ),
            Account_Map[Lvl 2] = "Total PR Tax"
        ),
        0
    )
)
