DatesYTD inside a Calculate and Filter function, How?

I think i may have solved the issued by using the calculate inside another calculate function.

SelectedBalance YTD =

VAR CurrentItem = SELECTEDVALUE(IncomeStatement Dtls)

RETURN

SWITCH(

    TRUE(),

    CurrentItem = "Net Sales", [Net Sales YTD],

    CurrentItem = "Cost of Sales", [Cost of Sales YTD],

    CurrentItem = "Standard Margin", [Std Margin YTD],

    CALCULATE(CALCULATE(

        [Totals],

        FILTER(

            'Income Statement Dtls',

            'Income Statement Dtls'[Category] = CurrentItem

        )

    ),DATESYTD(Calender[Date]))

)
