I'm not sure what you're asking, Roberta. Once you enter information on your profile about the DNA test that you took, WikiTree will display that information on appropriate profiles. For autosomal DNA it goes up and down the tree for 8 relationship degrees, out to 3rd cousins, and back as far as 6th grandparents. It's only updated once a day, so you may have to wait up to 24 hours to see the information displayed.
To "make that happen", you select "DNA Test Information" from the drop-down under "Add" at the top right of your profile. That will take you to a page where you can enter information about each DNA test that you took. You cannot add DNA tests to WikiTree for other living people. They have to have their own profile and add their own tests.
I made my comments to Claude because he hasn't connected himself to his parents or anyone else on WikiTree. His DNA test information is only visible on his own profile. WikiTree can only display DNA results when people are connected.
