ActionScript 3.0 :: Access An Object Within A Class - Why Is Object Null

i am trying to access an object within a class and the object is comming up as null but i dont understand why.this is the object:

btnLMain = new MovieClip(); //variable declared earlier in code
btnLMain.name = "btnLMain";
btnLMain.clickNum = 0;
addChild(btnLMain);

this was created in the class: LanguageButton. here is how i declared the above class within the class i am trying to instantiate it:

var btnL:LanguageButton;

then i try to access the btnLMain from the LanguageButton Class and it, (btnLMain) is comming out null:

btnL = new LanguageButton(cssLoader);
main.addChild(btnL);
btnL.btnLMain.addEventListener(MouseEvent.CLICK, btnLClick);
