Analysis :: MDX Need To Filter Measures Based On A Dimension

I am pretty new to MDX and am having trouble getting what I need out of this MDX query. Some business rules:

Gross Amount applies to all clients, whether Type A or Type B.  I always want to return Gross Amount.Some clients are Type A, some are Type B, some are both, and some are neither.There are Type A Net Amount and Type B Net Amount values for all clients, but I only want to display the Type A Net value if the client is a Type A client, only Type B if the client is a Type B, or both for both, and neither for neither.  I would like to return blank/null, not $0.00, for those values that should not be displayed.

Here's the basic query.  

SELECT { [Measures].[Gross Amount],
[Measures].[Type A Net Amount],
[Measures].[Type B Net Amount]
} ON COLUMNS,
NON EMPTY {[Dim Client].[Parent Client Code].[Parent Client Code] *
[Dim Client].[Child Client Code].[Child Client Code] *
[Dim Client].[Is Type A].CHILDREN *
[Dim Client].[Is Type B].CHILDREN
} ON ROWS
FROM ClientInfo

Here's the DESIRED output........
