subtracting 2 measures

[brodaddy02]

I think I have a softball question, but I am not sure.  I have 2 measures that produce the correct results.

Measure 1) Distinct_Mentor_Group_Billets:=COUNTROWS(DISTINCT(tbl_Raw[UIC+BSC]))

Measure 2) Primary_Mentor_Group:=COUNTA(tbl_Raw[Primary Mentor Group])

Both columns contain text data.  I am trying to create a new measure that subtract the number of billets by the number of people

Desired Measure) Delta Group:=[Primary_Mentor_Group]-[Distinct_Mentor_Group_Billets]

The numbers are not working correctly.  Does anyone have a suggestion?

I have attached a picture of the data.  I am pretty new to posting.  I think I have to something wrong with filters.

Hi @brodaddy02 

Normally, it should works, but the exact result depends on what exactly do you need

As a very first "blind" suggestion try to obtain both of measures into CALCULATE()
