Camera lock

I'm trying to lock the camera onto a unit, but whenever I use the trigger - lock camera orientation to unit - the camera screws up. If you've played Zelda, Ocarina of time, in the market place, the camera follows Link, but stays in the same position, just turning around. How would I do this?

there are two lock camera triggers, one that you shose, and the other(forget the name) thats does what you want.

heres the map, it has the trigger on it :)
