That first one was pretty tough to follow! I played it about ten times before I realized you posted the second one!
A couple of things.
If you are on the actions for the correct choice, there is no need to put in the condition to check if the question is correct. It will only trigger if that choice is selected, so it is correct.
On the action list, the action to show the green message for 5 seconds does not stop the processing of actions, all of the actions in the list will be executed in order, so the “Link to scene” action immediately after is run, and it switches scenes.
What you are likely looking to do is show the green message, and then start a timer for 5 seconds (probably one that doesn’t show to the user), and having the scene switch on the “On Done” action for the timer.
