Help!!! how do I target a swf inside a movie?
I am able to load the swf movie on a clip event but how do target the swf to a posion within the novie?

If you want the swf to load at a certain spot inside the other movie, add this in frame 1 of the swf you want to load;

this._x = 50;
this._y = 50;

The top left corner will load to 50 and 50 of the parent movie.
