MIT App Inventor Help

I want to make a check box that if ticked than open a new window
and when unticked it will undo

When check box status changed set the checkbox enable to false and save the value as true or false in tinydb so that next time while screen load he can get the status

(As per the topic i have suggested )

It seems this is not one time check box..

Just drag a check box
When check box status changed
If checkbox checked = true
Set window to visible true
Else
Set window visible to false
