If I am not mistaken, you would have to have an emptyMovieClip placed on the stage with specific x, y values (i.e. mov._x = 10 mov._y = 10). This will place your emptyMovieClip on the stage and allow you to load your external swf into it.Try this:// This will load a swf into the emptyMovieClip mov_mc// Don't forget to adjust the x,y property values of mov_mc to your location of choice_root.yourButton_btn.onRelease = function() { loadMovie("your.swf", "mov_mc");};
