Help trigger external movie to load from button in another external movie - stuck!

I really hope someone can help me!!!

I am loading movie C.swf into movie B.swf which gets loaded into movie A.swf the main movie. All loading works except C.swf has buttons that need to trigger another movie E.swf to load into A.swf and that is not working!!!

Here is the structure I am using:

[COLOR=“Red”]A.swf (main final movie loads B.swf on start)
B.swf (loads main nav C.swf and scrolls it infinitely)
**C.swf **(main nav with buttons that trigger sub nav E.swf to load into A.swf)
E.swf (sub nav with buttons that trigger F.swf to load into A.swf)
F.swf (scrolling images of portfolio)[/COLOR]

The actionscript I am using for the button in C.swf to trigger E.swf to load into the main movie A.swf is:

[COLOR=“red”]metals_mc_bn.onRelease = function() {
reActivateMenu();
this.gotoAndStop(3);
this.enabled = false;
[COLOR=“Red”]loadMovieNum(“E.swf”, 1); // trigger sub nav E.swf to load into A.swf[/COLOR]
};[/COLOR]

I am so stuck with this and seems so simple a problem, but I’m just pulling hairs out at this point, can anyone please help me!
