I made some changes but its not working

Calc_Table = 

Var _Calc=
SUMMARIZE(Book1,Book1[MonthYear],Book1[Date].[Year],Book1[Date].[MonthNo],"OverAllCount",COUNT(Book1[Time]), "FilteredCount",COUNTROWS(CALCULATETABLE((Book1),Book1[Time]=2)))

Var _Pct_Calc=
ADDCOLUMNS(_Calc,"_Percentage",IF(DIVIDE([FilteredCount],[OverAllCount],0.00)=BLANK(),0.00,DIVIDE([FilteredCount],[OverAllCount],0.00)),"Date",DATE(Book1[Date].[Year], Book1[Date].[MonthNo],1))

RETURN _Pct_Calc

I added the Date column to return  month & year in date format and then created a new calculated column for rolling averages

Rolling3MonthAverage = 
CALCULATE(
    AVERAGE(Calc_Table[_Percentage]),                
    DATESINPERIOD(
        Calc_Table[Date].[Date],                 
        MAX(Calc_Table[Date].[Date]),           
        -3,                          
        MONTH                          
    )
)

But for some reasons it keeps showing blanks.I have no idea why is this happening.

Maybe some experts on the forum can help out.
