HI. Multiple screen algo

MIT App Inventor Help

Hi.

I want to go to Screen2 from Screen1 only once.

here is what I am doing.

When Screen1.initialize
if startvalue=0, then Open another screen Screen 2,
else if startvalue=1, call nextquestion

I go to Screen2, finish my activity on screen2.
Open another screen Screen1 with startvalue 1,

This works only once. Next time, it does not open Screen2, because start valuse remains 1

Instead of using Open another screen block again, you could simply use close screen block in screen 2. So, this will provide no start value to screen 1 and the screen will stay where it was when the other screen was opened.
