MDX query for Concatinating Date parts

HI All,

I am runnning the following MDX query, but I am not getting the expected output.

WITH  MEMBER [Measures].[Full Date] as 'NOW()'

MEMBER [Measures].[What Day] as 'DAY([Full Date])'

MEMBER [Measures].[What Month] as 'MONTH([Full Date])'

Member [Measures].[What Year] as 'YEAR([Full Date])'

MEMBER [Measures].[Test] as 
[What Day] + "-"  + ([What Month])  + "-"  + ([What Year]) 

SELECT
   {[Full Date],[What Day],[What Month],[What Year],[Test]} ON COLUMNS
FROM [Adventure Works]

For the Test measure I want the output as 10-1-2013, rest of the Measures giving the correct answer.

I want to concatinate the rest measure into the Test measure and want that result.

Please help me to accompolish this.
