I have 3 lists, first is a list of possible items, second is a list of people and the third is list of which people have what items. I am trying to find a way to display which items people do not have. Example below
People
- Adam
- Bob
- Carl
Items
- Apple
- Rice
- Water
Paired list
- Adam has Apple
- Adam has Water
- Bob has Apple
- Bob has Rice
- Carl has Water
I am trying to reverse the paired list to what items people do not have. IE
- Adam does not have Rice
- Bob does not have Water
- Carl does not have Apple
- Carl does not have Rice
Is there a way to accomplish this?
