MDX Current Month Problem

Question

Hi all,

I have the following MDX query:

WITH
   MEMBER [Measures].[TY Sales]
   AS 'SUM([Measures].[Sales])'
   MEMBER [Measures].[YTD Sales] 
   AS 'SUM(PERIODSTODATE([Time.Fiscals].[2009], [Time.Fiscals].CurrentMember), [Measures].[Sales])'
   MEMBER [Measures].[LY Sales]        
   AS 'SUM(PARALLELPERIOD([Time.Fiscals].[2009].[8], 1, [Time.Fiscals].CurrentMember),[Measures].[Sales])'
   MEMBER [Measures].[LYTD Sales]
   AS 'SUM(PERIODSTODATE([Time.Fiscals].[2009], PARALLELPERIOD([Time.Fiscals].[2009].[8], 1, [Time.Fiscals].CurrentMember)), [Measures].[Sales])'
SELECT
   {[Measures].[TY Sales],[Measures].[YTD Sales],[Measures].[LY Sales],[Measures].[LYTD Sales]} ON COLUMNS,
   [Time.Fiscals].[2009].[8] ON ROWS
FROM
   [Sales]

The above query displays sales for fiscal year 2009 and fiscal month 8 (Feb), I would like the fiscal year and fiscal month dynamic but I'm unsure on how to do this?

I'm using Mondrian.

Thanks!
