Movie Clip Within A Movie Clip

I have the following code in an external swf called “test”:
clients_bn.onPress = function () {
_root.createEmptyMovieClip(“container”, 1);
loadMovie(“paper.swf”, “container”);
container._x = 65 ;
container._y = 250;
}
portfolio_bn.onPress = function () {
_root.createEmptyMovieClip(“container”, 1);
loadMovie(“portfolio2.swf”, “container”);
container._x = 100;
container._y = 250;
}

I have the same type of code for navigation on my main swf. Within the the main page I have a button that opens the external test.swf I mentioned above. The swf opens but when I press the buttons within the external swf the other external files within this swf (paper and portfolio2) do not open.

I guess what I’m trying to do is have a button from my main page open an external swf and I want a button within that external swf to open another external swf. I’m relatively new so I tired my best word this. Any input would be much appreciated!!! Thanks…
