attachMovie woes

I got my xml portfolio to duplicate movie clips for the thumbnails via attachMovie and it’s all working great except for one thing. The mc animation only plays for the last thumbnail and not all of them. I’ve been searching the forums for a clue, but I’m afraid I’m in over my head on this one. I don’t even know what to search for. :q: Can anyone help?
Here’s the code.

function GeneratePortfolio(portfolio_xml) {
	var portfolioPictures = portfolio_xml.firstChild.childNodes;
	for (var i = 0; i<portfolioPictures.length; i++) {
		var currentPicture = portfolioPictures*;
		var currentThumb_mc = form_mc.attachMovie("thumb_mc", "thumb_mc"+i, i);
currentThumb_mc.onRollOver = currentThumb_mc.onDragOver=function () {
			info_txt.text = this.title;
			currentThumb_mc.play();
		};
		currentThumb_mc.onRollOut = currentThumb_mc.onDragOut=function () {
			info_txt.text = "";
			currentThumb_mc.play();
		};
