So I have a list ZZZ as so: ID 1 2 3 and another list XXX as so: ID Name 1 A 2 B 3 C Now I'm trying to create a list where on one column I will have a drop-down column AA with ID from list ZZZ and another column BB where I will have a drop-down that gets its data from Name in XXX as per selection on AA. How do I achieve that? I made AA of type Parent Drop Down List and was able to populate it from ZZZ. But I can't populate BB accordingly. I made BB of type Child Drop Down List and selected XXX as my list and put in the following values: Column for Value: Name Column for Text: Name Column to Join to Parent: ID ...and when I go to my list and add item, I see that column AA is well-populated and column BB is not. Furthermore, when I select another option from column AA, I get the following error: One or more filed types are not installed properly. Go to the list settings page to delete these fields. HELP
