COUNTIF Question

HI all,

I have a data set with columns like this:

 

Donor ID  Staff Donor

01             TRUE

02             TRUE

02             TRUE

03             FALSE

04             FALSE

05             TRUE

06             TRUE

07             FALSE

07             FALSE

 

I want to calcuate the percentage of staff donors to all donors. My thought is first to calcuate the number of staff donor first by distinct count donor ID if staff donor = TRUE. I created a new measure like this:

 

Number of staff donors = CALCULATE(DISTINCTCOUNT('SOS Appeal'[Lookup ID]),'SOS Appeal'[Staff donor] = "TRUE")
 
When I tried to visualise the new measure in a card this to see if my DAX is correct it shows an error message, even though the DAX itself has no red flag...
 
Also, this method probably is not the quickly way to get percentage? I would love to know if there is a better solution.
 
Many thanks for your help.
 
Keep well and stay safe!
 
Diana

    The error could be that it is a boolean column and you are comparing it to text? Not sure, can you click the More details and post what it says? Also is Lookup ID correct or Donor ID? Whatever your final formula, you can get percentage by right clicking, Show as and then Percent of Total.

    DianaT If it's the boolean that's being problematic, you could try these:

     

    Number of staff donors = CALCULATE(DISTINCTCOUNT('SOS Appeal'[Lookup ID]),'SOS Appeal'[Staff donor] = true())
     
    Number of staff donors = CALCULATE(DISTINCTCOUNT('SOS Appeal'[Lookup ID]),'SOS Appeal'[Staff donor] =1)
     
    Number of staff donors = CALCULATE(DISTINCTCOUNT('SOS Appeal'[Lookup ID]),'SOS Appeal'[Staff donor])
     
    Also, is [Lookup ID] the same as your [Donor ID]?

      Hi,

       

      Thank you so much for your help. I changed the filter to [Staff donor] = true() and it is working like a dream now!
