Count rows if Col1 AND Col2 are blank

Please explain the issue again and provide some sample data and expected outcome.

Hi, Anonymous 

Based on your description, I created data to reproduce your scenario.

CurrentTable:

AnotherTable:

You may create a measure as below.

Result = 
var _col1 = SELECTEDVALUE(CurrentTable[Col1])
return
IF(
    _col1 = "1",
    CALCULATE(
        COUNT(AnotherTable[Col2]),
        FILTER(
            ALL(AnotherTable),
            AND(
            AnotherTable[Col3]=_col1,
            AnotherTable[Col2]=BLANK()
            )
        )
    )
)

Result:
