You need to set the value for a global variable named RunningTotal to 5 and navigate to the previous
screen named MainScreen.
Which formula should you use?
A . UpdateContext( { RunningTotal: 5 } ); Navigate( MainScreen,
ScreenTransition.Cover, RunningTotal );
B . If( Value(TextBox1.Text) >= 0, (Set( RunningTotal, 5);
Back();), Color.Green )
C . UpdateContext( { RunningTotal:5 } ); Back()
D . Set( RunningTotal, 5 ); Back();
Answer: D
Explanation:
You set the value of the global variable with the Set function. Set( MyVar, 1 ) sets the global variable MyVar to a value of 1.
Use the Back and Navigate function to change which screen is displayed.
