PreLoader causing component problem

Question

Hey all,
I have a created a site that has a scene preloader that
preloads my main.swf.
My main.swf then has a preloader for each external .swf file
loaded into it.
Everything seems to work it preloads my main.swf showing the
percent loaded.
Once it's loaded it appears and then loads an .swf file into
a loader component (this works)
Problem:
the buttons inside the external .swf (that is loaded into my
loader component) do not work. What could be wrong?
I'm thinking it's just a problem with the scope. Below is my
script I'm using.
thanks in advance,

I have a loader component on a layer in my main movie named
"bgLoader".
In my actions layer in my main movie I also have the code
below:
mcLoader.addListener(mcListener);
mcListener.onLoadProgress = function (target_mc,
bytesLoaded,bytesTotal) {
extLoader_mc._visible = true;
var pctLoaded = Math.round((bytesLoaded/bytesTotal)*100);
extLoader_mc.pctLoaded_txt.text = pctLoaded;
extLoader_mc.loaderBar_mc._xscale = pctLoaded;
if(pctLoaded>=12){
extLoader_mc.loaderBar_mc._visible=true;
if(bytesLoaded >= bytesTotal){
extLoader_mc._visible = false;
mcLoader.loadClip("intro.swf", bigLoader);
then in the file that is loaded into my bgLoader I have
buttons both component and _mc's and neither will load.
the code for the buttons in the .swf that is loaded into
bgLoader (loader component) is
// comboBox.value = hello.swf
component_btn.onRelease = function () {
if(comboBox.value == "defaultValue"){
warning_txt.text = "Select Option";
}else{
warning_txt.text = ""; // works!
//_root.mcLoader.loadClip("hello.swf", _root.bgLoader);
_root.bgLoader.loadMovie(comboBox.value);
trace(comboBox.value); // works!
};
