unloadClip function doesn't work

programming flash
1

this.dots_btn.onRelease = function() {
myMCL.loadClip(“dots/interiordots.swf”,1);
}

this.dots_btn.onPress = function() {
myMCL.unloadClip(“homeimage.swf”);
}

I have this on frame 10. THe loadclip function works, but the unloadclip function does not. Is this not how unloadclip works, or how you are suppose to right it? The button is on the main stage and the “homeimage.swf” was loaded on frame 1 into level 2.

THANKS!!!
