Hi all,
How can i get (mdx) the next member in Axis ?

Sample mdx:

select
{[Time[.[2001],[Time].[2003],[Time].[2005]} on columns
{[items.[all items].children} on rows
from SalesCube

I would like to add a calculated member that calculates
the variance between each column (i can't use prevmember or nextmember
since the selected columns are not consistent in their
dimension location).
