Multiple Condition into Value

Thank you parry2k , I totally missed that.

I think the logic is reversed.  All of them are always >= 1 so you are always getting the result from [s.330ml1].

Try it like this, I changed it to a SWITCH to make it easier to read also.  I also removed the table name in front of the measure.  You should NEVER include the table name when referencing a measure.

Samurai330ml12 =
SUMX (
    VALUES ( 'All Master Data Customer'[Customer Code] ),
    SWITCH (
        VAR _Value = [Samurai 330ml] 
		RETURN 
			TRUE (),
			_Value >= 24, [s.330ml24],
			_Value >= 12, [s.330ml12],
			_Value >= 6, [s.330ml6],
			_Value >= 3, [s.330ml3],
			_Value >= 2, [s.330ml2],
			_Value >= 1, [s.330ml1],
			BLANK ()
    )
)

Chanleakna123 based on what jdbuchanan71  provided. I would recommend to store measure value in a variable because of performance and for each change:

Samurai330ml12 =
SUMX (
    VALUES ( 'All Master Data Customer'[Customer Code] ),
    VAR __value = [Samurai 330ml]
    RETURN
    SWITCH (
        TRUE (),
        __value  >= 24, [s.330ml24],
        __value  >= 12, [s.330ml12],
        __value  >= 6, [s.330ml6],
        __value  >= 3, [s.330ml3],
        __value  >= 2, [s.330ml2],
        __value  >= 1, [s.330ml1]
    )
)
