I see what the problem is right away.  else if level = 2 or 3 then expertise = 'Medium';  It should be level=2 OR level=3.  

 

What I don't understand is the code produces this output?  Any explanation would be nice.  Thanks.

@mcypert16 May I ask where these questions are coming from?

Yes.  They are from a website called  BI exam academy.  I understand the question now.  The else if level=2 or 3 is always true because 3 is nonmissing and not 0.  So the code never gets past line 3.
