How to use _root to load file from HDD

Question

I have main moviclip.Inside this movieclip I have 2 layers.
On the 1st keyframe of layer1 I have _root to moviclip to load
[ _root.section != "a.swf"; {
_root.section = "a.swf";
_root.transition.gotoAndPlay("closing"); ]
thing is this is not leading me to the a.swf. I need to know
the road to that a.swf.
P.S. If I have the 2 layers on scene1 the path, shown above,
works

Answer 1

nowhere in that tutorial do i see that mangled script.. first
of all, brackets are array access operators, and do not belong
anywhere in what you gave, which means syntax error. second, you
don't have an ending curly bracket, which means syntax error..
third, your opening curly bracket is doing nothing because you
haven't defined anything in an if statement, another syntax error.
fourth, there is nothing in the code you provide that loads
anything. This is probably what it should be
if(_root.section != "a.swf") {
_root.section = "a.swf";
_root.transition.gotoAndPlay("closing");
which is saying... if, on the root timeline the variable
section doesn't equal a.swf, then on the root timeline, the
variable section equals a.swf, also on the main timeline, the movie
clip with instance name transitions needs to goto and play frame
labeled closing.
"I repeat...it's not a sintax error.....this is code for
loading external movie wich has connection to preloader code and so
on.."
you are wrong, there is nothing right about this script, this
doesn't load anything.
