I have a query that combines 3 different tables. When all three fields are filled in, the records populate, but not the records that don't have all 3 fields. When I apply what I learned in Beginner lvl 5 and use the 'Is Null' function to find those records that don't have the 3rd field, it populates no results. I want it to show all records even if it's missing one of the fields.
