Switch Function not calculating

Hi Experts

I have the following switch statement which is returnng back "no result" as opposed to the [Margin Pecent] value...

Total Margin = SWITCH(
SELECTEDVALUE('Date Calculations'[Date Calculation]), 
    "Local Margin", CALCULATE(CALCULATE(
        [Margin Percent]
        ,
        FILTER( ALL(Profitability[DIM_POSTING_DATE_SK]),
            CONTAINS( VALUES('DateFilter'[DIM_DATE_SK]),'DateFilter'[DIM_DATE_SK], Profitability[DIM_POSTING_DATE_SK] ) )
         )
,
FILTER (
        ALL ('DateFilter' ),
        'DateFilter'[Quarter Nbr] = MAX ('DateFilter'[Quarter Nbr] )
            && 'DateFilter'[Full Date] <= MAX (DateFilter[Full Date])
    )

     ),"")
