Create a set of the two members in a crossjoin and then do a sum on it.

So something like

WITH MEMBER [YourCalculation]

AS

SUM

(

{([Country].[Country].&[India] , [State].[State].&[Andhara])}

,

[Amount]

)

Although of course you have provided very little detail so I've had to provide a generic example - in other words don't just copy and paste that code, it won't work. Also it's pretty poor form for you to just ask people to write your code for you 😉
