I have an entry that duplicates it, help me please

I have an entry that duplicates it, which I use to register the name of one of the members of a team. but when when I write in the original “juan” in the duplicate “juan” appears and when I try to modify it by “pedro” the original also changes to “pedro”. I need to keep two different names on the form at the same time, I do not know if it is with repeater, but I do not know how to use it. Someone could show me an example how the code would be written with the input text. I’m waiting for your help
Thank you for your collaboration and forgiveness for the bad English help me please with concrete examples. Thank you
