Counta in an Power Query if statement

[mathias1998]

Hi,

I am trying to make an if statement for a new custom column, where the rows will:

- have -1 if the row in the old column contains a date

- have 0 if the row in the old column contains null

- have the count of non-empty rows from the old column if the date is 01.09.2022 (essentially what would be COUNTA([old column] in dax).

I have the following code, where "insert right formula here" is the part I need help with:

= each if [old column] = #date(2022,9,1) then "insert right fomula here" else if [old column] = null then 0 else -1

Any help will be sincerely appreciated!

replace "insert right fomula here" with:

List.NonNullCount(PreviousStepName[old column])
