FL8pro: Need some simple actionscript help!

Just wondering if anyone can give me any hints or even help to give me the code for this please!?

If object1(movieclip) moves to frame 30, button1 and button2 will turn blue and green.
If then, button3 is clicked, object2(movieclip) moves to frame 30.
If button4 is clicked, only button1 will remain blue.
Click object1(movieclip) and it moves to frame 60.

At this stage, if any other buttons are clicked on stage, nothing will happen and msgbox displays to tell users this.

Button3 and then button4 must be clicked ONLY one more time. If user clicks on it more than this, nothing happens and msg box displays.

Please help me. I really need this. Thank you so much.
