List Viewer & Firebase DB Help

Hi,
For my app the user will sign in using Firebase authentication and it will navigate to a page where they will enter a name and a number in two different text boxes and press enter. Then it will save in the Firebase db and navigate to the main page(where all the name and numbers can be seen from other users).I was wondering since I am not able to join text in the list viewer, how can I get the name and number entered beside each other in one list viewer? Then when the user enters another name and number, that should come below the previous.

Thanks

Can you try dataviewer with airtable instead?
You’ll find it easier to implement.
