[AccessD] why isn't this working?

Hi Pedro

You still may have mistyped something.
Try with a minimum expression:

   SELECT
     IIf([Code]='542',[Telling]*0.2,0) AS Resultaat_Telling
   FROM
     TellingCode;

If this doesn't work something else is wrong.
If it works, replace 0 with another IIf() construction and so on.
