Hey,
I have a data validation drop down list in one cell (A1), the fields of which each have Indirect subcategories in B1. So if for example, I select Fruits from the drop down in A1 (other fields: Vegetables, Dairy), then the list in B1 will only have Apples, Oranges (and not Broccoli, Milk, etc.)
Is there a formula or code I can use to highlight any errors in this dependency? I.e. If I choose Fruits, then Apples, but go back and change Fruits to Vegetables, Apples will still be in B1.
Thanks!
