    Hi qasimawan ,
    sorry, yes, the code has to be adjusted:
    if List.Contains(#"query1"[Concat], [Concat]) then "true" else "false"

Hi Imkef, 

 

Many thanks for your reply! 

 

Unfortunately, I have ran into this error which I can't eliminate. I have added a change type step and manually changed the data types but the error hasn't gone away. 

 

Here is the error message: Expression.Error: We cannot convert a value of type Table to type List.
Details:
Value=[Table]
Type=[Type]
