Inserting one animated button .fla inside another one

[FONT=Franklin Gothic Medium][FONT=Lucida Sans Unicode]I need some help to insert a animated (scale) button inside another button.

Already tried to insert it as a mc in the scene of the larger button but the scale animation doesn´t work.
If you want the file, to test, please send me a message

Any ideia?
