CS4: How do you create a flash presentation?

For a school project we have to make a presentation about our RME topic, and we can to it in any format we want.
I want to do it in Flash so as to add interactivity.
Problem is, I am not certain on parts of it.

QUESTIONS
-How do you add buttons, so as to change the background?
For example, it shows title screen. Then you click. Then it shows first slide like. Then you can click like, Introduction, The Pillars of Islam, ect.

Thats pretty much it...
So how do I do it?

You have two options. You could either have each "slide" on a frame, or you could load them onto one frame as needed. It would be easier to put them on separate frames. Basically, just make the buttons link to other frames. Say you have a slide on The pillars of Islam, so you name the slide "Pillars". If you did that, you would use this code for the button (in AS 2):

PHP Code:

---

btnName.onPress = function() { 
       gotoAndStop("Pillars");
} 


---

Thanks!
EDIT:I tried this, but it it have me this(Warning: 1090: Migration issue: The onPress event handler is not triggered automatically by Flash Player at run time in ActionScript 3.0. You must first register this handler for the event using addEventListener ( 'mouseDown', callback_handler).) error...

Ah, well, you notice how I said "(in AS2)"? That is actionscript 2. If you are using 3.0, I'm afraid I can't help you further. Sorry!

Oh, ActionScript 2
I dont mind what ActionScript I do it in, but it works!:)
