Help with something

I made a game
http://stickgame.50webs.com/index.htm

But I don't want the stickman to walk right off the screen! What can I do about this? I am using Flash 8 Pro

you can make an _x test
if((hero._x+hero._width/2)>Stage.width)return;//dont udate the _x value
else{
//udate it here}

I don't really understand that.
