Variables - validity in screens

Hello.
Is a global variable defined e.g. in screen1 valid, visible also in screen2 .... 3 .... 4 etc?
Or how do I solve it?

No.

Use TinyDB, or better yet, don't use multiple screens.
Stack vertical arrangements, and show only one at a time.

But when I have a menu on screen1 according to which I want to display individual html files, how do I do it in multiple verticals?

Hello.
If I want to do this by having a menu on screen1 and I want to display various html files on screen2 according to that menu, then the menu identifier should probably be stored in TinyDB ... if I understood correctly .... Does anyone have a link? I got into a time crunch ...
Thanks for any help.
