Help with buttons?

Hello… I have recently over the past two months gotten into flash.

Well, I am having a problem with buttons…

Whenever I click the button that plays frames, it plays the frames, and never stops playing…

Example:

Click “Hi”
Plays an animation…
Plays all the other animations…
Restarts.

How can I fix this, to where it will stop it?

(Note: I edited it back in, but I forgot what I said before…?)

Edit, Fix:

When you want the animation to end, just click on the frame you want it to stop on, and go to actions:

It should say “Actions - frame”.

Click it, and add the “stop();” tag there…

My second question:

How can I create multiple scenes?

Edited with answer: Go to insert > Scene.
