Still need help :( loading outside files in actionscript

Question

Ive been all over the forums online trying to get this
problem fixed and no one has really settled it for me (its been
MONTHS)
So I'm going to attempt to be as in depth as possible and
post code as well.
Heres the deal- its a portfolio site, www,darrenlasso.com
The problem is when i load multiple swf files into levels.
When i first call on an outside swf from a button inside the main
file the code looks something like this:
on(release){
_level1._visible=false;
loadMovieNum("cover.swf", 1);
cvrbtn._visible = false
acibtn._visible = false
When from inside THAT file, I want to return back to the MAIN
navigation file, the code looks more like this:
on(release){
mcl.addListener(mclListener);
mclListener.onLoadInit = function(mc:MovieClip){
mc._visible=true;
mc.gotoAndPlay(76);
_level1._visible=false;
mcl.loadClip("darnen.swf", 1);
Ive messed around with the code so many times now trying
everyones different suggestions that i dont even know if that is
the code I have live right now but i know its not working how i
want it to. The problem seems to be that i can only load into level
1, and when i do that, going between these various calls on outside
files there is a 'flicker' of a frame or two of the OLD previously
loaded file that will play BEFORE the new one initiates. As this is
a portfolio site it needs to be polished so i can't have stuff like
this plaguing it. Its been unfinished for months now because i just
can't figure it out. Please please help me if you can.. hopefully
you like a challenge because i just havent been able to get the
help i need from anywhere else :/

Answer 1

when i load the swf from outside, i want it to then be able
to return to the main navigation file which i guess would be level
0. So does that mean that the code for buttons navigating back to
the main flash file would be more like:
on(release){
mcl.addListener(mclListener);
mclListener.onLoadInit = function(mc:MovieClip){
mc._visible=true;
mc.gotoAndPlay(76);
_level1._visible=false;
mcl.loadClip("darnen.swf", 0);
As i load in all these different files from outside I've been
loading them all into level 1 because that seems to be the only way
to get them to display at all with the code I'm using. I assume it
might be better to load them all into individual levels? I'm not
sure. I'm still just kinda learning AScript as i go along..
