Onload levels issue

Question

I have a main banner that loads 3 other banners. When the
main one loads the others, part of the main banner is behind the
loaded ones. I want the main banner to be in the front and the
onload banners to be behind. How do I fix this? Here's my code.
_root.createEmptyMovieClip("container", 1);
loadMovie("banner1.swf", "container");
container._x = 0;
container._y = 0 ;
_root.but.onPress = function () {
_root.createEmptyMovieClip("container", 1);
loadMovie("banner1.swf", "container");
container._x = 0;
container._y = 0;
but.gotoAndStop(2);
but3.gotoAndStop(1);
but2.gotoAndStop(1)
but2.onPress = function () {
_root.createEmptyMovieClip("container", 1);
loadMovie("banner2.swf", "container");
but2.gotoAndStop(2);
but.gotoAndStop(1);
but3.gotoAndStop(1)
container._x = 0;
container._y = 0;
but3.onPress = function () {
_root.createEmptyMovieClip("container", 1);
loadMovie("banner3.swf", "container");
container._x = 0;
container._y = 0;
but3.gotoAndStop(2);
but.gotoAndStop(1);
but2.gotoAndStop(1)

use swapDepths() to move your main banner to a depth above
your depth 1 loaded banners.
