Converting to 3rd Person from 1st Person - Island Demo

I am using Lerpz (3d platformer tutorial) to manuver through the island demo (no long using the FPS). The question is, I can get Lerpz in there fine, however, the camera doesn't follow Lerpz around. Even more, on the SpringFollowCamera script, I am getting an error: NullReferenceException: Object reference not set to an instance of object. Help on this would be appreciated. Thanks.

Add the "Third Person Camera" scrip onto Lerpz.
