AS3 Altering variable within movieclip's parent - actionscript-3

I am trying to alter a variable within the parent or root of a movieclip with:
this(root).variable
So far I've only encountered errors, and I'm not sure how to fix them. The variable is on the stage.
The current error is:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Stage#28b7ef99 to flash.display.MovieClip.
Does anyone know what I'm doing wrong?
It seems like that works for everyone else.

Did you mean :
this.root.variable
or
this.parent.variable

Try
Movieclip(parent).variable

Error #1010: A term is undefined and has no properties. at :MainTimeline/loop()_fla.MainTimeline::frame1:190]

im making a platform game and i can't figure out what's the problem specifically it says the problem is in this line:
if(background_mc.platform_mc.hitTestPoint(player_mc.x-xDistance,player_mc.y, true))
To solve this kind of problem you need to trace() all the objects you are referencing in this line prior to it:
trace("background_mc", background_mc);
trace("player_mc", player_mc);
trace("platform_mc", background_mc.platform_mc);
if(background_mc.platform_mc.hitTestPoint(player_mc.x-xDistance,player_mc.y, true))
One of the traces will give you either "undefined" or "null" and then you can move on to the next step: why do you think the object must be accessible while it is not.

AS3 - Error #1009 - But it's debug is referencing a function?

I've found lots of questions and answers about this error, but I'm having trouble because my error seems to referencing the function name and not any instance name on my timeline.
Error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mpu_fla::MainTimeline/playAnimation()
My Code
myButton.addEventListener(MouseEvent.CLICK, playAnimation);
function playAnimation(e:MouseEvent):void
{
animation_logosout.play();
}
stop();
I'm not quite sure it's telling me it can't find the function name? Any help would be greatly appreciated! I'm new to AS3!
Thanks!
animation_logosout is undefined. Check if the object is present on stage on the same frame, and check if the instance name is set correctly.

Reference Error 1056 Flash

I have googled and figured out the issue with my current problem is that I have the Automatically Declare Stage Instances box unchecked. The problem is that I can't figure out what I need to add to make it work properly, any help would be great.
ReferenceError: Error #1056: Cannot create property btnTwo on Main.
at flash.display::Sprite/constructChildren()
at flash.display::Sprite()
at flash.display::MovieClip()
at Main()
You mean with the "declare stage instances" unchecked? You need to declare them as public variables with the same name as the instance name on the stage (as far as I know! :) ).

What Does This Ember Exception Mean?

I'm getting the following error when creating a new record/model:
Uncaught Error: Attempted to handle event `willSetProperty` on <App.NewsItem:ember361:null> while in state rootState.loaded.created.inFlight. Called with {reference: [object Object], store: <App.Store:ember299>, name: bodyHTML}
What does it mean?
Seems to be caused by the application updating a property (called 'bodyHTML') on an instance of a model of type App.NewsItem while it is being saved (rootState.loaded.created.inFlight). I have no idea why I'm receiving the error on creation though.
Seems like either you are modifying an existing dirty object , or you are trying setting some property to undefined

Casting a retrieved Mediator with PureMVC as its proper class returns null

I have a mediator that I've registered for a navigation page:
facade.registerMediator(new NavPageMediator(viewComponent));
I'm trying to retrieve that mediator on another page like so:
var navPageMediator:NavPageMediator = facade.retrieveMediator(NavPageMediator.NAME) as NavPageMediator;
However, that statement returns null. If I try to cast it using the NavPageMediator(facade.retrieveMediator(NavPageMediator.NAME)) syntax instead, I get a TypeError: Error #1034: Type Coercion failed: cannot convert com.website.mvc.view.page::NavPageMediator#237560a1 to com.website.mvc.view.page.NavPageMediator.`
I can't, for the life of me, understand why NavPageMediator#237560a1 would be unable to convert to NavPageMediator, nor what happened in between registering the mediator and retrieving it that caused this. Especially since trace(new NavPageMediator() as NavPageMediator); returns [object NavPageMediator].
Incidentally, and this may be part of my problem, I don't understand what the #hash at the end of the object is (#237560a1). Is it simply an internal identifier for that class instance?
Edit:
Left a bit of important info: The SWF in which I instantiate and register the mediator is separate from the SWF in which I try to retrieve it.
Figured it out. It turned out to be an ApplicationDomain issue. Assigning both SWFs (the registrant and the retriever) to the same domain solved the issue.
Additionally, I'm pretty sure the #hash at the end of the class name is an internal reference to the ApplicationDomain to which the class belongs. So NavPageMediator#237560a1 was in a different domain than NavPageMediator (why there was no hash on the second one I'm still not sure; that would have made things a bit clearer).
