Order function in the MDX

Hi Experts,

I have an issue with Order function I have Implemented my code like this 

  SELECT
NON EMPTY
    {
	[Measures].[Value]

    }
 ON COLUMNS 
 ,NON EMPTY
order(
	{
	 [Dim].[Inter].CHILDREN
	*[Dim].[Description].CHILDREN
	*[Dim].[Code].CHILDREN
	*[Dim].[Rank].[All].CHILDREN
	}
	,[Dim].[Rank].membervalue,bdesc
    ) 

   ON ROWS 
 FROM [Cube]

I want the results based on ranks in descending Order. I tried like above but it is not displaying in proper Order. I tried without 'b' before desc as well but still it is not working. Could anyone help me 

Thanks,
