How to have a record saved locally

Hello, by following an online tutorial I was able to create an app with 2 pages,
page 1 has an input field
page 2 has a text field that displays what is inputted from page 1
everything gets saved on local storage… so far so good

My issue, on page 2 where the text field is, I added a second text field that displays everything is shown on text field 1, (basically just a copy), I just cannot figure how to save this info, every time I close the app, the original text field is there but the new one resets to empty

I assume I need to create a new resource under the data tab
but to what do I assign that and will it be enough?

Total newbie here
