Wrong subtraction results between two variables

Hi samoberoi 

Thank you very much danextian for your prompt reply.

I did some testing and there doesn't seem to be anything wrong with your code. Running them individually gives the correct results, like this:

Do you want Subtraction_measure to display an equation? If so, you can use the following code:

Subtraction_measure = 
VAR A =
    CALCULATE(
        SUM('Table A'[Amount]),
        FILTER(
            'Table A',
            ('Table A'[Country] = "England"
            && 'Table A'[LType] = "Type 2"
            && 'Table A'[Tax Plan] = "GT Free Tax")
            ||
            ('Table A'[Country] = "Wales"
            && 'Table A'[LType] = "Type 2"
            && 'Table A'[Tax Plan] = "QT Free Tax")
        )
    )
VAR B = [Test]
VAR Result = B - A
RETURN
    FORMAT(B, "0.00") & " - " & FORMAT(A, "0.00") & " = " & FORMAT(Result, "0.00")

Here is the result.

If you still have questions, please provide your desired results. This is best presented in a table format.
