Problem with setPan!

loadMovie(“test.swf”,"_level1"); / this script is in my first frame…

ok… i have only music in test.swf… i don’t want to put my loaded movie from _level1

but i want to make my setPan get to work…

onClipEvent (enterFrame) {
pan = 2*_parent.panSlider.drag._x;
_level1.setPan(pan); // here is my problem !!!
_parent.panAt = Math.round(pan);

I donno… maybe i should just put my loadMovie into MC and somehow set it up with setPan… but donno exactly how… help me somebody…!
