Running Accumulative Share Pivot Table

[george456]

Dear Community

I need to calculate a running Percentage accumulative in a pivot table.

My Syntax is as :

rangeSum(Before(sum(if(Year2Date(MonthYr,0,if(Month(vMaxMonth)>11,1,Month(vMaxMonth)+1),vMaxMonth),$(vMeasure)))/
sum(TOTAL if(Year2Date(MonthYr,0,if(Month(vMaxMonth)>11,1,Month(vMaxMonth)+1),vMaxMonth),$(vMeasure))),0,ColumnNo()))

I am getting no output

Can you suggest a solution

Thanks

George
