morph targets script help

Can anyone please help me I have less time left for my project and I am stuck and urgently need help. Problem is

I have downloaded the morphtargets_384.unitypackage from the blog http://forum.unity3d.com/threads/15424-Morph-Target-Script

After having a look at this project I was creating my own project in that i created a gameobject named morpher and to that added my base head as mesh filter along with a mesh renderer. Now when i attach the morphtarget script with this game object my mesh data should be loaded in the morph target script area in the inspector window but this is not happening can anyone tell me how can my meshes get atatched to the mesh targets script am i missing any pice of code. By the way I have exported my mesh already from max.
