Target Stage and append from inside symbol????

Having trouble again. I am SLOWLY getting use to the CC 2014 thing =).

Now I need to be able to target a Symbol on the stage from within an element inside a symbol and append it with an <iframe> and pass attributes to the iframe.

I have a file -- please refer to the  videoui symbol and whitewater1.click and whiteawater2.click actions in that symbol (link below (Drop Box)

Here's what I have so far...

// insert code for mouse click here

// Go to a label or specific time and stop. For example:

// sym.stop(500); or sym.stop("myLabel");

sym.stop("videotwo");

// Change the text in an element

sym.$("video-text").html("Video by: TheNigglesbear");

var youtubevidtwo = $("<iframe/>");

sym.getComposition().getStage().getSymbol("vcontainer").append(youtubevidtwo);

youtubevidtwo.attr('type','text/html');

youtubevidtwo.attr('width','616');

youtubevidtwo.attr('height','347');

youtubevidtwo.attr('src','http://www.youtube.com/embed/eqzwoIQseyA?rel=0');  // url/Video_Id

youtubevidtwo.attr('frameborder','0');       // 1 | 0

youtubevidtwo.attr('allowfullscreen','0');   // 1 | 0

This same code -with different path to symbol of course- works fine on the stage document.compositionReady, but not sure how to target the videoui and append the iframe and its attributes to it from inside another symbol.

Help please -- there really needs to be more ADVANCED examples of possible methods of targeting. I find a lot about targeting symbols inside of symbols,or Stage to symbols, but not much on symbols to stage to another symbol also on the stage.

Thanks in advance.
