free form deformation

Hey. I need some help with ffd. It's based on the Bezier curves, it's working for sure(you can see how the green line changes while dragging some lattice points). The problem is I don't know how to attach my lattice to the game object vertices. Here's project link : http://www.mediafire.com/?vptcmjphzmxy5h2.
I'm not a programmer so I believe that all the scripts can be optimized. Thanks
