Script transition and button code won't work together

Hi

I’ve been experiementing with actionscripting transitions between sections… this is the first site I have tried this with (last 3 had swf loaded in one after another rather than transitioned between). I used some code from kirupa.com which works for loading movies in and out, but I also have some code for my movie buttons. I can get one or the other working, but not together, so I guess I’m clashing code somewhere, I could do with some help please to find what I’m doing wrong…

The transistion code and calling-up buttons is;


Menubar.b1.onRelease = function() {
	if (_root.section != "about.swf") {
		_root.section = "about.swf";
		_root.transition.gotoAndPlay("closing");
	}
};
Menubar.b2.onRelease = function() {
	if (_root.section != "portfolio.swf") {
		_root.section = "portfolio.swf";
		_root.transition.gotoAndPlay("closing");
	}
};
Menubar.b3.onRelease = function() {
	if (_root.section != "contact.swf") {
		_root.section = "contact.swf";
		_root.transition.gotoAndPlay("closing");
	}
};

and the code I have on my movie buttons is;


on (rollOver) {
	gotoAndPlay("rollover");
}
on (releaseOutside, rollOut) {
	gotoAndPlay("rollout");
}

Is there a way to combine them???

I have attached the fla file as well, if this helps.

Thanks. Wayne.
