Create categories based on a measure

[DoubleElle_2]

Hello,

I'm pretty new to Power BI so forgive me if my question is obvious for you all. 

I have a table called CALLS and I'd like to create two categories based on measure values. 

My measure is the one below:

call_numbers = CALCULATE(DISTINCTCOUNT(CALLS[call_ID]), FILTER(CALLS, CALLS[sms] = "1"))

I'm trying with something like this but it doesn't work as it should:

Categories=

SWITCH(

    TRUE(),

    call_numbers > 1 && call_numbers <= 3, "1-3",

    call_numbers > 3 && call_numbers <= 4, "4",

    BLANK()

)

Format:

CALLS[call_ID] = text 

CALLS[sms] = text 

call_numbers = int number 

I'm afraid that the problem could be related to the filter. 

Is there someone who can help me? 

Thanks in advance
