Attach movie - broken buttons - targeting

Question

Let's say i have a simple movie clip called "navBar" and in
that movie clip I have nested another movie clip called
"green_btn". I have assigned linkage to both clips the first as
"navBar" and the second "green_btn". It is removed from the stage
and saved in the library with proper linkage.
Now let's say I return to the stage and create a "holder" for
my attached movie. I leave it blank, I call it "myHolder_mc" and
assign it linkageand give it a instance name of "myHolder_mc" and
move the cross hairs to the upper right hand corner.
Then I create a red button movie clip on the stage of a red
circle called "red_btn", and give it a instance name of "red_btn".
I will use red_btn.onRelease to load up the attachedMovie. When I
press the red_btn, the "navBar" movie attaches fine.
OK, thanks for sticking with me this far - HERE IS THE
PROBLEM - I want to be able to target the "green_btn" that is
located in the original navBar and assign it a onRelease function.
I can't seem to be able to target it, and have tried to find the
right target path, but can't seem to do it correctly.
So here is the code so far that isn't working
red_btn.onRelease = function(){
myHolder_mc.attachMovie("navBar","navBar", 0)
// the green_btn is nested inside of the navBar movieClip
myHolder_mc.navBar.green_btn.onRelease = function(){
trace("hello")
What should I do?

If you are importing the swf into the library it will lose all its actionscript.  You need to either copy that file from its original fla and create it as a movieclip in your other file (copy its timeline into a movieclip) or load that swf dynamically when the file is running using actionscript.
