need general help with camerascript

okay here is the script for my camera currently it has everything i need it to do, but the problem is that i want the vector 3 relpos (relative position) sent to my movescript, what i want it to do there is to determine the forward direction for the character. you know when you have a third person game you rotate your camera around your character and you press W he starts walking in the direction the camera is facing. so if anyone has any tips on: getting this script to make friends and communicate. make it function the way i want. cleaning up this nightmare of badly placed variables. thank you.
