Why does my Measure only works on certain rows ?

[Anonymous]

Hello everone, 

I'm into my third week of using DAX in PowerBI and stumbled upon this hurdle where my measure only calculates certain rows but not all like what I would have hoped for. 

On the screenshow below, "Decline rate next 5 years_dynamic" and "Decline Rate Dynamic_S" are both measures I have created. 

"Decline Rate Dynamic_S" is just a score (1 to 5 score) that is assigned to the asset based on the magnitude of "Decline rate next 5 years_dynamic". My problem is that it assigns a score for most of the assets but left out some - see arrow picture below - and this just puzzles me. My intention is for it to assign scores for all the rows/assets. 

The code I have written for "Decline Rate Dynamic_S" is

Decline Rate Dynamic_S =
VAR Score1 = CALCULATE(SELECTEDVALUE('Score Tranches Input'[Decline Rate_SA]), 'Score Tranches Input'[Index] = 1)
VAR Score2 = CALCULATE(SELECTEDVALUE('Score Tranches Input'[Decline Rate_SA]), 'Score Tranches Input'[Index] = 2)
VAR Score3 = CALCULATE(SELECTEDVALUE('Score Tranches Input'[Decline Rate_SA]), 'Score Tranches Input'[Index] = 3)
VAR Score4 = CALCULATE(SELECTEDVALUE('Score Tranches Input'[Decline Rate_SA]), 'Score Tranches Input'[Index] = 4)
VAR Score5 = CALCULATE(SELECTEDVALUE('Score Tranches Input'[Decline Rate_SA]), 'Score Tranches Input'[Index] = 5)
RETURN
IF([Decline rate next 5 years_dynamic] <= Score1, 1,
IF([Decline rate next 5 years_dynamic] <= Score2 && [Decline rate next 5 years_dynamic] > Score1, 2,
IF([Decline rate next 5 years_dynamic] <= Score3 && [Decline rate next 5 years_dynamic] > Score2, 3,
IF([Decline rate next 5 years_dynamic] <= Score4 && [Decline rate next 5 years_dynamic] > Score3, 4,
IF([Decline rate next 5 years_dynamic] > Score5, 5)))))

Any help on this would be very much appreciated.

Seems your nest If missing the condition of 4<[Decline rate next 5 years_dynamic] <=5, You can try the following DAX and see if it works

Decline Rate Dynamic_S =
VAR Score1 =
    CALCULATE (
        SELECTEDVALUE ( 'Score Tranches Input'[Decline Rate_SA] ),
        'Score Tranches Input'[Index] = 1
    )
VAR Score2 =
    CALCULATE (
        SELECTEDVALUE ( 'Score Tranches Input'[Decline Rate_SA] ),
        'Score Tranches Input'[Index] = 2
    )
VAR Score3 =
    CALCULATE (
        SELECTEDVALUE ( 'Score Tranches Input'[Decline Rate_SA] ),
        'Score Tranches Input'[Index] = 3
    )
VAR Score4 =
    CALCULATE (
        SELECTEDVALUE ( 'Score Tranches Input'[Decline Rate_SA] ),
        'Score Tranches Input'[Index] = 4
    )
VAR Score5 =
    CALCULATE (
        SELECTEDVALUE ( 'Score Tranches Input'[Decline Rate_SA] ),
        'Score Tranches Input'[Index] = 5
    )
RETURN
    IF (
        [Decline rate next 5 years_dynamic] <= Score1,
        1,
        IF (
            [Decline rate next 5 years_dynamic] <= Score2,
            2,
            IF (
                [Decline rate next 5 years_dynamic] <= Score3,
                3,
                IF ( [Decline rate next 5 years_dynamic] <= Score4, 4, 5 )
            )
        )
    )
