I don’t really understand what it is that you are trying to do in terms of relating “Points” and “PointsLinked”
Basically the relationship of creating “DataType A” and “DataType B” where “DataType A” has a data field that is of the type “DataType B” means that when you search for “DataType A” you can pull up all the information stored in that particular “DataType A’s Data Type B”
So if you have a datatype “User” and data type “Contact Details” you put in “Contact Details” some data fields like phone, email, address etc.
Then on the “User” data type you put a data field and make it of type “Contact Details” and maybe label it ‘ContactDeats’…then when creating a ‘User’ your next step would be to create ‘Contact Details’ and the third step would be to ‘make changes to thing: result of step 1’ and for ‘ContactDeats’ data field put ‘result of step 2’…
So when you search for that ‘User’ you can pull up ‘Users’ ContactDeats’
