[MX] Elastic Easing

I looked at ilyas’s tutorial on elastic easing but I can get it to work, I need to ease ( I can do normal easing but I want it to be eleasticy ) a MC to a position on a button click but I cant think how to do it. When I did get it to move it moved the whole _root around, that was doing the MC moving onClipEvent(enterFrame) and using the _xmouse and _ymouse not preset positions.
