Why is this DAX suddenly returning nothing?

[duncfair]

I inherited this report and am not DAX fluent. [OrderFunnelAmt] has values, so I am at a total loss here.

Please let me know if and what else I need to troubleshoot this.

SelectedOrdFun =

VAR Mth = [SelectedKPI_Month]

VAR CY = IF(vw_FiscalCal[IsDecember] = 1, [Current_FY] - 1, vw_FiscalCal[Current_FY])

VAR Qtr = [SelectedKPI_Qtr]

RETURN

    SWITCH (

        [SelectedKPI_Time],

        // FY

        1,

            CALCULATE (

                [OrderFunnelAmt],

                REMOVEFILTERS ( vw_FiscalCal ),

                vw_FiscalCal[FiscalYear] = CY

            ),

        // YTD

        2,

            CALCULATE (

                [OrderFunnelAmt],

                REMOVEFILTERS ( vw_FiscalCal ),

                vw_FiscalCal[FiscalYear] = CY,

                vw_FiscalCal[FiscalMonthofYear] <= Mth

            ),

        // QTD

        3,

            CALCULATE (

                [OrderFunnelAmt],

                REMOVEFILTERS ( vw_FiscalCal ),

                vw_FiscalCal[FiscalYear] = CY,

                vw_FiscalCal[FiscalQuarter] = Qtr,

                vw_FiscalCal[FiscalMonthofYear] <= Mth

            ),

        // MTD

        4,

            CALCULATE (

                [OrderFunnelAmt],

                REMOVEFILTERS ( vw_FiscalCal ),

                vw_FiscalCal[FiscalYear] = CY,

                vw_FiscalCal[FiscalMonthofYear] = Mth

            )

    )

Hi @duncfair ,

I looked at your dax and according to your description, your DAX returns empty.
For this DAX, it is important to be clear whether you are creating measures or creating new columns. If it is a measure, then whether the "[SelectedKPI_Month]" in your VAR Mth = [SelectedKPI_Month] is another measure, you can't use the column name to get the data here.
For you to return null, my advice to you is that when you define a variable every time, you use return to verify the value of the variable to see if it is caused by a variable calculation error.

Thanks. I will dig in further, but the variables in question are the selected slicer values on the page.
