Remove all on a timeline

I have a movie with multiple scenes.
scene 1 and scene 2.

i have an intro and a few other things that go on in Scene 1 but it’s all done with AS other than the background image. I made a button with nextScene(); in the on(press). When clicked, it goes to the next scene (1 frame with a stop() action).

The problem is that it continues to put all the stuff from Scene 1 on there. So is there a way to either flush everything from Scene 1 with the on(press) as well or just stop it from doing any more functions once the button is pressed?
