Need serious help in coding animation regarding XML

programming flash
1

So, I created a falling animation. I copied the motion as AS3. I pasted it in the area I want my character to fall.

But when I run my codes, i got an error saying I’m accessing undefined property “fall”

Here’s my motion codes.

var fall_animator:Animator = new Animator(fall_xml, fall);
fall_animator.play();

How do I solve it so that I can put this code in my game ? I also do not know how or where I can create XML file.

Thanks.
