Why won't this code work?

This is my code, but the buttons don’t work in live testing on any phones. However, they will work on the computer’s preview and navigate the screens.

I don’t know, to be honest but I wouldn’t use special characters in screen names, only you see them
and a wait block is not needed in less you are intending for a wait

Question do you have them buttons in side of a layout. may be ifso take them out of the layout and see how Intractable in a .apk
