i would like to add a custom column in Power Query.
The if function is supposed to to check to different columns, the first regarding "not assigned" the second regarding not blank. The generating the output. However, there is the error message occuring "Expression.Error: The name 'BLANK' wasn't recognized. Make sure it's spelled correctly"
Appreciate your support!
if[#"Notification.Notification Level 01.Status Decision Made (Name)"]="Not assigned" and [Notification End Dat.Notification End Dat Level 01]<>BLANK() then "DLF" else "no error"
