2 Part Question : Stop movie animation/Load movie animation

Question

Okay I am a VBA guy and taking on a project in Flash. So 72
hours into it I am going nuts on a simple problem = P. I read a
tutorial from
http://www.echoecho.com/flashbuttons02.htm
about how to make animated buttons. All went well, I was able to DL
the FLA and really see the inner workings. However. When I mouse
over I want the move to play but not loop. I can't get it to stop.
I want my button to go from black to alpha 20% and stay on mouse
out, 20% alpha - black. That code on the site makes it loop, which
is very unappealing. (Also in the FLA they use grouped graphics,
what the advantage to that?)
So second part. In my button I would like the "down" to
enable another .swf to open and play on the other half of my page
setup. Am I coding onpress() on the down part of the button or
elsewhere in the FLA.
I wanted to attack my fla file but i guess you can't.
regardless if ppl need to see more of what I am doing then I can
host it on my site. I figured this is pretty basic stuff that once
I know I will get it.

- This is a site that I liked. It has the nice buttons like I am
trying to build and then on mouse clicks it changes the other side
of the page. That is what I am aiming for.

Answer 1

like i said, completely take out your button now.. then place
a black rectangle on stage with whatever text you want the button
to say on top of it, then select both and create new Movie Clip..
on frame 1 insert stop();.. on frame lets say 10 (can be whatever)
make keyframe, and make the the assets 20% alpha, also put a
stop(); action on the frame..
now back to the main timeline, click your new Movie Clip,
give it instance name of whatever ex: my_mc..
now place this code on the main time line on a keyframe, not
on the movie clip, on a keyframe, my guess is it will be frame one.
my_mc.onRollOver = function() {
my_mc.gotoAndPlay(2);
my_mc.onPress = function() {
container_mc.loadMovie("your.swf");
//container_mc is blank Movie Clip on stage.. all this means
is to create a movie clip with nothing in it, place it on stage and
give it an instance name of container_mc... this is what your swf
will be loaded into.
im giving a link to an example.. if you click frame 1 of the
'actions' layer, and replace where it says yourSWFname.swf with
exactly what its asking, it should work just without a hitch.
Here is the
