Access of undefined property AS3, i dont understand

Ok, so I'm watching this tutorial: http://as3gametuts.com/2012/01/08/platformer-3/ and when

For some reason this code won't work:

xSpeed -= scrollY;
ySpeed -= scrollX;

back.x = scrollX;
back.y = scrollY;

And calls for

1120: Access of undefined property scrollX 1120: Access of undefined property scrollY

Have you added the vars scrollX and scrollY to your code? In the source they're declared right above xSpeed around line 16.
