Count distinct reporters between certain times

I am looking to create a table with the count of distinct reports between two times.
–Example–
TIK-1 – Reporter (John Doe)
TIK-2 – Reporter (Mark Stock)
TIK-3 – Reporter (John Doe)
TIK-4 – Reporter (Chris Twain)
TIK-5 – Reporter (Mark Stock)
TIK-6 – Reporter (Bob Foss)
TIK-7 – Reporter (John Doe)

Count Distinct Reporters - 4

–END OF EXAMPLE–

Right now I use this Count(DISTINCT([Reporter].CurrentMember)) but this does not give me the correct result.

Thanks for any help!

Hi,

The count function in MDX must be applied to the set.

Nonzero(Count( 
 Filter(
  [Reporter].[User].Members,
  [Measures].[Issues created]>0
  )))
