Using a function in multiple scenes

Question

I have a .fla project being created under CS4, using
ActionScript 3.0, that consists of multiple scenes.
In the code attached to the first scene, I define some
functions that are used as methods on buttons:
function MouseDown(TheKey:Object):void
TheKey.alpha=0.6;
function MouseUp(TheKey:Object):void
TheKey.alpha=1.0;
function AlphaPoint6(event:MouseEvent):void
MouseDown(event.currentTarget);
function AlphaonepointO(event:MouseEvent):void
MouseUp(event.currentTarget);
And I use a couple of the functions as EventListener methods
on buttons
Key1.addEventListener(MouseEvent.MOUSE_DOWN,AlphaPoint6);
Key1.addEventListener(MouseEvent.MOUSE_UP,AlphaonepointO);
So far so good.
Then, I create a second scene in which I have some other
buttons.
When I try using the same functions as eventlisteners on
these buttons, in the code for the second scene:
Key11.addEventListener(MouseEvent.MOUSE_DOWN,AlphaPoint6);
Key11.addEventListener(MouseEvent.MOUSE_UP,AlphaonepointO);
then, I get the error messages
1120: Access of undefined property AlphaPoint6
1120: Access of undefined property AlphaonepointO
BUT, if I try declaring these functions again with the script
of the second scene, I get the error message
1021 Duplicate Function definition
So, I seem to be stuck between a rock and a hard place. On
the one hand, when the compiler parses the second scene, it
believes those functions are defined (as it is not happy if you try
defining them again). On the other hand, the compiler does not
think they are defined. as it considers them to be undefined
properties.
Does anyone have an idea about how to resolve this conumdrum?

One option is to not use scenes. Just take what you have as
scenes and either place them in the one timeline, or convert them
into movielcips. In my own design work, I have never used scenes.
When I first encopuntered them via someone else's design, I
immediately disliked them because it meant I had to search thru
inobvious places to find things that needed to be revised. Other
folks that help in these forums have their own reasons for
promoting not using scenes... troublesome, unreliable, outdated,
etc
