It will not open the new screen when I press the button on the notifier please help
You used the wrong Notifier block.
Use the one with two buttons.
Ok thank you, the final part is I need the score number from the game screen to the leader board screen is there a way I can transport numbers to a different screen
save each number in TinyDB then look them up in the other screen.
It's much simpler to use stacked Arrangements in one screen than to use multiple screens.
Just let one arrangement be visible at a time, and you will have access to all your variables and procedures.
