Error with MDX query -- measure not calculating properly

Question

Hi all,
I have a calculation in my dataset [Currentsalesperiod]. Basically it gives me a set of all the sales periods, and than it takes the last value. However, when I use this calculation in my dataset, it only shows me the rows with the sales period 6.
I have a feeling that the currentmember basically takes my whole output as a set and than calculated the sales period. When I use this in my nonempty on rows it only shows data for sales period = 6.
How can I solve this?
WITH
SET [CurrentSalesPeriod]
AS
TAIL(
NonEmpty(
             [Point of sale].[Management period].[Management period],
             {[Measures].[Sales amount]}
YTD([Date invoice].[Bonus calendar - Week].[Bonus week of year].&[2014]&[52])
             * [Point of sale].[Client id].CurrentMember
       ),1
SELECT
NonEmpty(
             ([Point of sale].[Client id].[Client id]
*[CurrentSalesperiod]
             ,[Measures].[Total YTD Sales]
on rows,
     [Measures].[Total YTD Sales] 
on Columns
FROM
    [RETAIL cube]

Hi Y,
I am not sure your calculation is doing what you want. As I read it, the set is simply the first non empty Management period that has a value for YTD. The result from your query is a list of all Client Ids, for that Management period, irrespective of Date
Invoice. Is that what you want?
