Calculate Cumulative Month Value in MDX

Question

I wanna calculate the cumulative values by month/year

My dimensions period as follow:

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?

Sorry, i don't know how can i reply you answer. I've added another answer with your suggestions — Tonny Alves, Feb 01 '19 at 15:51
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, Feb 01 '19 at 15:53
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, Feb 01 '19 at 15:57
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, Feb 01 '19 at 16:02
Well, its worked when i removed "[Período].[Nome de Mês].[Nome de Mês]". But I need this field. How can i combine this 2 fields in sum? — Tonny Alves, Feb 01 '19 at 16:12
I presume that [Período].[Nome de Mês].[Nome de Mês] is a more detailed feild than [Período].[Mês], in that case use [Período].[Nome de Mês] in the calculated member. — MoazRub, Feb 01 '19 at 16:33
I add [Período].[Nome de Mês].[Nome de Mês] in calculate member construction and finally works. Thanks @MoazRub for help. — Tonny Alves, Feb 04 '19 at 13:14
