Filter calculated members

I'm trying to create a calculated member that is using 2 dimension members only.

This MDX produces the results I want the calculated member to have:

select  {[measures].[Amount],[measures].[Asset pool Yield]} on columns
from [Financials]
where {[Account].[Account type].&[D], [Account].[Account type].&[T]}

I thought this would work for the calculated member:

With member [Measures].[Test] AS
AGGREGATE({[Account].[Account type].&[D], [Account].[Account type].&[T]}) * {[Measures].[Amount]}

I also tried this:

Filter( CROSSJOIN ([Account].[Account type].&[D], [Account].[Account type].&[T]),
 [Measures].[Amount])

But both generate #ERROR for Measure Test.  What's the best way to do this ?
