percent of parent

[jiuba]

Hello. I have a problem with the calculated members.
When I have to calculate the total percent for two or more dimension I put this code

([Measures].[Part]/([Measures].[Part ],[Country].[All Country],[Product].[All Product]))

and its ok but the problem if a have to calculate the percent of a ancestor or a parent of two dimensions. If I put this code

([Measures].[Part]/([Measures].[Part],[Country].parent),[Product].Parent)

the result is always bad but if I put this code(the same but only for one dimension)

([Measures].[Part]/([Measures].[Part],[Country].parent))

its ok.

Can you help me please. Thanks.
