load movieclips sequentially

I'm making a big flash movie which contains many separate flash files ( like a big puzzle and it's pieces ), but I want to load these files sequentially. So when the first movie has been loaded than it starts loading the second. Here's a piece from the AS:

var arrPaths:Array = new Array();
for (var k:Number=1;k<=9;++k) arrPaths.push(k+".swf");
var arrX:Array = new Array();
var arrY:Array = new Array();
load_btn.onRelease = function () {
for (i=0; i<nSwfCount; i++)
{
crtSwf = mcHolder.createEmptyMovieClip("swfHolder"+i, i);
crtSwf.loadMovie(arrPaths[i]);
crtSwf._x = arrX[i];
crtSwf._y = arrY[i];
}
}

Thank you,

then just wait untill a movie clip is loaded, and load the next one.
