I wanna calculate the cumulative values by month/year

My dimensions period as follow:

Period Dimension

I ve tried any ways to perform this operation, but unsucessfull

with member [Measures].[Valor Acumulado] 
as Sum(PeriodsToDate([Período].[Mês].[(All)]),[Measures].[Valor Pago]
)
 with member 
 [Measures].[Valor Acumulado] as Sum(YTD([Período].[Mês].[(All)]),
 [Measures].[Valor Pago])

Or the cumulative calcule does not work or appears a Error Message

CellOrdinal 1 VALUE #Error Query (2, 37) The YTD function expects a member expression for the argument. A string or numeric expression was used

Query execution Query execution

Is it necessary to make a concatenation with Year and Month members?

Anybody to help me?

could you attach a screen shot of how you are expecting the result to be. – MoazRub
Sorry, i don't know how can i reply you answer. I've added another answer with your suggestions – Tonny Alves
take a look at the screen shot. Is this how the result shot be. If not share a screen shot showing how you want the result to look like. – MoazRub
you missed the Case statement and the " : " try this in your code [Measures].[Valor Acumulado] as Case when [Measures].[Valor Pago] = null then null else Sum({[Período].[Mês].firstchild : [Período].[Mês].currentmember},[Measures].[Valor Pago]) end – MoazRub
I don't have null values, but i've add the case statement with member [Measures].[Valor Acumulado] as case when [Measures].[Valor Pago] = null then null else Sum({[Período].[Mês].firstchild:[Período].[Mês].currentmember},[Measures].[Valor Pago]) end Is not cumulating :/ I don't know what is wrong – Tonny Alves
