# Promedio de sumas en consulta MDX

How can I compute average of sums in MDX? I want to compute sum of spending for each person and then compute an average of it. I have the following query so far, but I believe it gives me wrong result:

``````WITH MEMBER [Measures].[Average] AS
AVG(Measures.cost)
SELECT [Measures].[Average] ON COLUMNS
FROM
( SELECT Measures.cost ON COLUMNS,
{Person.[Last name].MEMBERS}*
{Person.[First name].MEMBERS} ON ROWS
FROM Cube )
``````

You just need to put in the first argument of Promedio the set of your persons.

``````WITH MEMBER [Measures].[Average] AS
AVG(Person.[Last name].MEMBERS * Person.[First name].MEMBERS, Measures.cost)
SELECT [Measures].[Average] ON COLUMNS
FROM Cube
``````

The result is closer to the right value, but still not there :) The average should be between 100 and 1000, the result was slightly over 4000. - kyooryu

@kyooryu Could you check that there are no unexpected elements in `Person.[Last name].MEMBERS`? - Benoit

Ah, I copypasted the answer as it was, I did not notice that last name is not crossed with first name. - kyooryu

Try to create a calculated measure for this function like this

``````IIF (([Measures.cost] > 0), AVG(Person.Members,Measures.cost),null)
``````

Then use this calculated measure in your MDX query

``````SELECT Person, 'calculated.measure'
FROM Cube
``````

This is only a sample code to illustrate the function.
