Dimwit MDX count problem

i have run small problem. have dimension identifies types of bills. have measure reports how many bills have been issued. there several types of bills. 1 of these adjustment bill. correction existing bill. these represented "a" bills in db

i need count number of unique bills, that's count of bills other "a" bills.

i've looked @ calculated members struggling mdx syntax.

anyone have pointers or articles should read?

 

it should this:`

with member [measures].[num]

as 'sum(except([bills].[level name].members, [bills].[ ]), [measures].[numbills])'
