Can't get movie clip to communicate with its parent...

If you do the following in the move that throws the error, what will it trace?

for (var i:uint = 0; i < root.scenes.length; i++) {
    var scene:Scene = root.scenes;
    trace("scene " + scene.name);
}

As for the Events, they provide an awesome way to use loose object coupling - making them self sufficient. In your case it could be  reverse info exchange. Instead of relying on the existance of root in your consule2 you can just dispatch an event that will be listened wherever (including root) and act accordingly.

function gotodsHome(event:MouseEvent):void{

     dispatchEvent(new Event("move_on"));    
}

On the timeline of your top move you could write (considering that counsul2 is the name of the clip):

consul2.addEventListener("move_on", moveOnHandler, true);

function moveOnHandler(e:Event):void{

     gotoAndPlay("FullLoaded","01_Landing_Page");

}

This way consul2 is not dependent on root and root, in turn, is just sitting and waiting when something will give an order to do something. There are many nice extensibility opportunities with this approach. For instance, several different clips can tell the root to go somewhere not having even a slightest idea what root is and, for that matter, not caring about outside world at all. Like "I let everyone know that this thing happened and I don't give a damn what you do with this information."
