1119 error: access of a possibly undefined parameter after preloader [renamed]

programming flash
1

ok…after my preloader i instantiate a screenHandler class which in turn instantiates a transitions class that has a public static property “exitFrames”.

When i try to check exitFrames from within the screenHandler class i get a 1119 error (access of a possibly undefined parameter …) below please find the code for the screenHandler AND the code for the transitions class. And once you find those please tell me what the bleed i’m missin’. My mom assures me that i’m smart but here we are.

the error occurs in here:

if(transTimer == transition.exitFrames){
                    removeOldScreen();
                    makeNewScreen();
                    transTimer = 0;
                    this.removeEventListener(Event.ENTER_FRAME, switchScreens);
