Creating movieclips with jpg and text, _y position

Hi,
I am trying to create a movieclip, load a jpg into it, and if successfull, create another movieclip (or even better: create that movieclip right away too), with a textfield in it, and place it under the loaded jpg, depending on the postion and height of the jpg. I tried something like this, but the jpg and text don’t show. I am sure it’s full of mistakes, and you probably don’t know where to start, but I was hoping someone could show me what is wrong:

this.createEmptyMovieClip("nieuwsfotoMC", 2);
nieuwsfotoMC._x = 15;
nieuwsfotoMC._y = 194;
var loadFoto:LoadVars = new LoadVars();
loadFoto.load("steef.jpg", nieuwsfotoMC);
loadFoto.onLoad = function(success) {
	if (success) {
		this.createEmptyMovieClip("NK1MC", 1);
		NK1MC.createTextField("NK1", 2, 15, NK1MC._y, 165, 0);
		NK1.multiline = true;
		NK1.wordWrap = true;
		var NK1fmt:TextFormat = new TextFormat();
		NK1fmt.font = "Verdana";
		NK1.size = 12;
		NK1.setTextFormat(NK1fmt);
		loadText = new LoadVars();
		loadText.load("nieuwstekst.txt", 1);
		loadText.onLoad = function(success) {
			if (success) {
				NK1MC.NK1.html = true;
				NK1MC.NK1.htmlText = this.tekst;
				NK1MC.NK1.autoSize = true;
				NK1MC._y = nieuwsfotoMC._y+nieuwsfotoMC._height;
			}
		};
	
};

Thank you very much,

Jerryj.
