How do I record a list of players?

I am trying to do a game where we can use the Text Input box to key in the Player name and when I clicked the Submit button (black colour) it will record the Player name at the backend and I can continue to key in the next player’s name.

Then after the system record all the Players, I can use the Next button (green colour) go to to the next Player on the list and Back button (blue colour) to go to the Previous Player on the list.

Thanks a lot for the help!
