Dynamic movie clip reference, invoke function in mc

1

Happy new year all!!

I’d like to invoke a function inside a mc from it’s parent, but I want to have the reference to the clip be dynamic. When I path the mc directly and invoke the function it works, how would I make that same reference work dynamically.

Here’s a sample of what I’m trying to do:

var myArr:Array = new Array();
myArr[0] = "galleryContainer_mc.eventGallery1_mc.imgContainer_mc";
trace(myArr[0]);

// This works
toggle_btn.onRelease = function() {
	galleryContainer_mc.eventGallery1_mc.imgContainer_mc.videoToggle();
}
// But this doesn't work
toggle_btn.onRelease = function() {
	myArr[0].videoToggle();
}

I know I’m fried, but that seems like it should work, am I missing something really basic here? Any advice would be really helpful at this point. Thanks!
