Adding 3rdd layer of script to stage

I don’t really know how to explain well here.
Basically I have 3 as files. Let’s call it A, B & C

A is the menu files
B is the files that gets the data from A, and tell C and others what to do
C is the data

After I’ve been trying around the scripts for a very long time,
i only manage to realise that if I did not use addChild at the main layers of files,
the object will not be shown in the stage.

for example,
ActionScript Code:
[LEFT][COLOR=#0000ff]private[/COLOR] [COLOR=#0000ff]static[/COLOR] [COLOR=#000000]var[/COLOR] zoomer:theZoom = [COLOR=#000000]new[/COLOR] theZoomCOLOR=#000000[/COLOR];
[COLOR=#0000ff]public[/COLOR] [COLOR=#0000ff]static[/COLOR] [COLOR=#000000]function[/COLOR] somethingCOLOR=#000000[/COLOR]:[COLOR=#0000ff]void[/COLOR] [COLOR=#000000]{[/COLOR]
zoomer.[COLOR=#000080]zoomOut[/COLOR]COLOR=#000000[/COLOR];
[COLOR=#000000]}[/COLOR]
[/LEFT]

I’m using direct calling instead of addChild B to A, because B doesn’t really have any object in it.
it just a function that communicates between A & C.

now after C get the data of A from B, even i use addChild in it, the object doesnt add on to the stage. any idea how i can solve this through files C?

C’s AS
