Call a function in an externally loaded SWF?

is it possible to call a function in an externally loaded swf from _level0 ?

Sceneraio

I have “mySwf” with “myFunction” in it.

I have “myMovie” which loads “mySwf”

can I call

this.mySwf.myFunction();

It dosn’t seem to work for me… lemme know if im missing something… thanks!
