Applying already working grow/fade function to previously loaded swf (mc container)

1

Through some previous as help, I am using this code to scale & fade an attached movie:

_root.attachMovie("logo","logo",10001)
_root.logo._xscale = 10;
_root.logo._yscale = 10;
_root.logo._x = 500;
_root.logo._y = 400;
_root.logo._alpha = 100;

MovieClip.prototype.grow = function(a,b) {
	this._xscale += b;
	this._yscale = this._xscale;
	if (this._xscale>a-1 && this._xscale<a+1) {
		delete this.onEnterFrame;
	}
};
_root.logo.onEnterFrame = function() {
		this.grow(250,50);
		if (this._alpha <= 100)
		{
			this._alpha -= 4;
		}
		else{
			delete this.onEnterFrame;
		}
}

Now, I would like to do basically the same thing with a movie that I have previously loaded into to an empty movie clip, called holder12, which occurs at a 34 second interval…I want to run the code to scale & fade the clip at about 70 seconds.

Here is one of my non working attempts:

MovieClip.prototype.EBSgrow = function(a,b) {
	this._xscale += b;
	this._yscale = this._xscale;
	if (this._xscale>a-1 && this._xscale<a+1) {
		delete this.onEnterFrame;
	}
};
_root.holder12.onEnterFrame = function() {
	clearInterval(EBSgrow);
		this.EBSgrow(250,50);
		if (this._alpha <= 100)
		{
			this._alpha -= 4;
		}
		else{
			delete this.onEnterFrame;
		}
}
EBSgrow = setInterval (EBSgrow, 70000);

I am wondering do I even need to code to check if the movie is loaded? (since I know it is)

Because I have gotten this working (below) but it just jumps to x and y scale values provided and the important part is that I scale & fade in a gradual transistion…

//function growEBS(){
	//clearInterval(growEBS);
//_root.holder12.onEnterFrame = function() {
		//_root.holder12._xscale = 500;
		//_root.holder12._yscale = 500;
		//delete this.onEnterFrame;
//}
//}
//growEBS = setInterval (growEBS, 70000);

I appreciate any suggestions on how to get this working and feel free to point out any mistakes I am making (because my basic understand of as is lacking, I sometimes put things together than any one with more experience would know cannot go together)
