How do you transfer data between two screens?


I am passing on a question from a student who is participating in an App Challenge competition.  I am not a computer programming teacher but am a teacher sponsor.  They are trying to transfer data from one screen into another.  How is that done.

How to pass values from one screen to another screen by Scott

Use different screens wisely
Before starting to create another screen, first you should think about is it really necessary? See also Building apps with many screens and SteveJG's post about advantages/disadvantagesbecause in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed... See also Martyn_HK's example about how to use Tabs in App Inventor and another example from Cyd.

Also, you can transfer data from screen to screen via databases or files to read.
