FIRSTNONBLANK returns blank

[tylermontney]

I want to return a columns first non blank value.

LastLogon = FIRSTNONBLANK('TestReport'[Account_Name], 1) & " was the last to logon."

Unfortunately, it returns nothing. I can verify the column I'm referring to has at least one value.

FIRSTNONBLANK ( 'TestReport'[Account_Name], 1 ) +1

use this query

 I think this would be solved problem

The formula you provided should work if the rest value of column Account_Name is Blank(except value "tyler.montney"). Now the formula does not get the expected value, so I assume the rest value of the column Account_Name is not Blank, it is empty("").

In this case, the following formula should work:

LastLogon = 
CALCULATE (
    FIRSTNONBLANK ( 'TestReport'[Account_Name], 1 ) & " was the last to logon.",
    TestReport[Account_Name] <> ""
)

How would you compare "blank" and "empty". As in null/nothing blank?

I can see "empty" being a whitespace as a value. Above is an example of what blank should be (where a comma delimted value has absolutely nothing in it).
