as2 hittest coordinates help

[Bum-Secks]

i can't seem to figure out how this should work. What i'm trying to do is create a hittest that's a certain length and not just a single coordinate.
if(this.hitTest(_root.box._x, _root.box._y>0, true)&&this.hitTest(_root.box._x, _root.box._y<50, true)){
this.dosomethingcool("pls");
}
with this script, instead of the guy hitting the coordinates of the box, it's only reacting to the coordiantes of the stage. How do i use greater than and less than for stuff like that?

You can't.

You need to define certain points at a distance apart, or use a for loop.

damn there goes my plans for the hittests. It'll probably work better if i use invisible mc hittests rather than having a bunch of loops running though
