Expression.Error: We cannot convert the value "" to type List.

Hi community,

I'm real new to powerBI and am getting this error in the following nested if statement:

Nested if statement:

 

= Table.AddColumn(#"Added Custom1", "Custom", each if [HRStreamDesc] <> "Nursing" then null else 
if List.ContainsAny([BaseClass],{"AN","ANCSD"}) then "Assistant in Nursing" else null)

 

Error message I am receiving:

 

Expression.Error: We cannot convert the value "QNG6" to type List.
Details:
    Value=QNG6
    Type=[Type]

 

Any assistance on how to overcome this would be appreciated.

Basically I need to create a new column based on the value that exists in another column, should be a simple nested if statement...

Cheers

Carl

    Hi CarlBlunck ,

     

    Please try:

    if [HRStreamDesc]<>"Nursing" then null else if List.ContainsAny( {[BaseClass]},{"AN","ANCSD"}) then "Assistant in Nursing" else null

    Hi CarlBlunck ,

     

    I used { } To convert the Value to List type.

    Hi CarlBlunck ,

     

    Please try this

     Table.AddColumn(#"Added Custom1", "Custom", each try if [HRStreamDesc] <> "Nursing" then null else 
if List.ContainsAny([BaseClass],{"AN","ANCSD"}) then "Assistant in Nursing" else null otherwise null)

      Hi mussaenda thanks - but I unfortunately get a "Token Eof expected" error and the otherwise statement is being highlighted.

        mussaenda ah I missed the inclusion of the each try if element.  That got rid of the error but now everything is just coming back as a null...

      Hi Anonymous thanks so much!  To help me understand, what does the addition of the {} brackets do to the [BaseClass] column?

      Cheers
