How to load a page with this AS to my web

Hi everybody,
im doing a flash site (according to kirupa tutorial: http://www.kirupa.com/developer/mx/full_site.htm).

Everything works great. But… One of pages containig AS is loaded (i see what is written there) but is not working at all (its a drawing board, but i cant draw there). Im not sure, maybe its AS that is compatible or what…

to load a movie (external fla) to my website i use thei code:
on (release) {
** _root.contents.loadMovie("…swf");
*
}

*one of my pages i want to load is a drawing bord using this code (source once again kirupa) but I CANT DRAW THERE ONCE ITS LOADED:

*_root.createEmptyMovieClip(“line”,1);

_root.onMouseDown = function(){
line.moveTo(_xmouse,_ymouse);
line.lineStyle(1,0x000000,100);
this.onMouseMove = function(){
line.lineTo(_xmouse,_ymouse);
updateAfterEvent();
}
}
_root.onMouseUp = function(){
this.onMouseMove = null;
}
*
I dont know what to do - how to repair it - i d like it works.
than you for help.
