True/False column with blanks - how to count the blanks

[sharpedogs]

Hi, 

I have a table with two seperate columns that are both True/False. But there are also blanks in those columns. I want to calcualte the number of rows in both columns where both of them have a blank. 

A sample table below. I want to return a count of 1, because Jack has a blank in both columns. 

Users     Has Exchange    Has OneDrive
Bob               TRUE             TRUE
Jack
Sam              FALSE            False
Dave             TRUE

It seems like this might be a good case for a calculated column

1. Use a Calendar table. A custom Date tables is preferable to using the automatic date/time handling capabilities of Power BI. https://www.youtube.com/watch?v=FxiAYGbCfAQ
2. Build your data model as a Star Schema. Creating a star schema in Power BI is the best practice to improve performance and more importantly, to ensure accurate results! https://www.youtube.com/watch?v=1Kilya6aUQw
3. Use a small set up sample data when developing. When building your measures and calculated columns always use a small amount of sample data so that it will be easier to confirm that you are getting the right numbers.
4. Store all your intermediate calculations in VARs when you’re writing measures. You can return these intermediate VARs instead of your final result  to check on your steps along the way.

You can create a measure using the SUMX iterator.

Hi @sharpedogs 

try a column

Column = calculate(countrows('Table');
FILTER(ALL('Table');ISBLANK('Table'[Has Exchange]) && ISBLANK('Table'[Has OneDrive]))
)
