How can i use the gotoAndStop function if my stage is a sprite in actionscript3?

Question

so i am working on a game that is very siilar to tony.pa's tile-based tutorials I have this function.

function isTeleporter (xt:int, yt:int):Boolean 
    {
        if(currentMap[yt][xt] == 105)
        {
            return true;
        }else
        {
            return false;
        }
    }

In my everyframe function i have this

if(isTeleporter(hero.xtile, hero.ytile))
           {
               myParent.gotoAndStop(2);
           }

It gives this error 1061: Call to a possibly undefined method gotoAndStop through a reference with static type flash.display:Sprite.

I believe it is because to generate the game in the first frame i have this

import TBGEngine;
//call new tbg with Sprite as parameter, tbg will place all visible objects inside this sprite
var mygame:TBGEngine = new TBGEngine(this);

I want to be able to switch frames and have a new level that on the new frame or a credit screen or an animation or something, but currently i have no idea how to do so. Any help is greatly appreciated! Im a sixteen year old highschool student in a small town with no computer science program at my school, so im pretty much on my own.

You cannot use gotoAndStop() on Sprite because Sprite does not have this method - it is not intended to be used with animations. Imagine Sprite as a simple one-framed Movieclip. Whenever you want to use animations inside of a DisplayObjectContainer you MUST use MovieClip. Same if you are subclassing Sprite - your subclass will not be able to go to any frame.
