Remove future dates in DAX expression for running total

Hi,

Ideally I would like to adjust the DAX expression so that future dates from my running total (quick measure) calculation do not appear in the graph.  Currenty they appear as a horizontal line.  I have used quick measure to generate the following code:

Count of CSR_NO running total in Month =
   CALCULATE(
      COUNTA('MY_DATA'[CSR_NO]),
        FILTER(
            CALCULATETABLE(
                SUMMARIZE(
                     'MY_DATA', 
                      'MY_DATA'[CSR_CREATE_DATE].[MonthNo],
                       'MY_DATA'[CSR_CREATE_DATE].[Month]
                 ),
           ALLSELECTED('MY_DATA')
          ),
      ISONORAFTER(
         'MY_DATA'[CSR_CREATE_DATE].[MonthNo], MAX('MY_DATA'[CSR_CREATE_DATE].[MonthNo]), DESC,
          'MY_DATA'[CSR_CREATE_DATE].[Month], MAX('MY_DATA'[CSR_CREATE_DATE].[Month]), DESC
      )
   )
)

I am aware this topic has come up a few times but the suggestions to add IF(ISBLANK(CSR_NO), BLANK(), CALCULATE(etc)

did not work.

How may I filter out future dates (from TODAY()) ?

Any help would be much appreciated.

Thank you,

Phil,
