Camera switching with iTween Touch

Hello I am using iTween to control the Camera on a path with Touch (or arrow Keys)

This script (below) works well and gives me a visual editor (yay) But now I want to SWITCH to a New path and still control it with touch

it's a PITA

So I guess the easiest thing is on an event (like a mouse Up) where I want to switch to a new path

is just switch to a New Camera with the same Camera follow Path script on it

Maybe? But it's not working and I am perplexed

Here is My Main Camera follow Path Script:

 using UnityEngine;
 using System.Collections;
 
 public class FlythroughCameraController1 : MonoBehaviour {
     public Transform[] movePath;
     public Transform[] lookPath;
     public Transform lookTarget;
     public float percentage;
     //public Transform[] path;
     public float speed = 0.1f;
 
 
     private float redPosition = .16f;
     private float bluePosition = .53f;
     private float greenPosition = 1;
 //    private float purplePosition = 1.2;
 
     
     void Start(){
     }
 
     void Update () {
         if (Input.touchCount > 0) {
             
             Touch touch = Input.GetTouch(0);
             
             if (touch.phase == TouchPhase.Moved) {
                 percentage += touch.deltaPosition.x * speed / Screen.height;
                 percentage = Mathf.Clamp01(percentage);
                 // ROBERTBU                iTween.PutOnPath(gameObject,path,percentage);
                 iTween.PutOnPath(gameObject,movePath,percentage);
                 iTween.PutOnPath(lookTarget,lookPath,percentage);
                 transform.LookAt(iTween.PointOnPath(lookPath,percentage));
                 //transform.LookAt(iTween.PointOnPath(path,percentage+.05f));
             }
         }
 
 
         if(Input.GetKey(KeyCode.UpArrow))
         {
             percentage += speed * Time.deltaTime;
         }
         if(Input.GetKey(KeyCode.DownArrow))
         {
             percentage -= speed * Time.deltaTime;
         }
         percentage = Mathf.Clamp01(percentage);
         iTween.PutOnPath(gameObject,movePath,percentage);
         iTween.PutOnPath(lookTarget,lookPath,percentage);
         transform.LookAt(iTween.PointOnPath(lookPath,percentage));
     }
 

     void OnDrawGizmos(){
         iTween.DrawPath(movePath,Color.magenta);
         iTween.DrawPath(lookPath,Color.cyan);
         Gizmos.color=Color.black;
         Gizmos.DrawLine(transform.position,lookTarget.position);
     }
     
     void SlideTo(float position){
         iTween.Stop(gameObject);
         iTween.ValueTo(gameObject,iTween.Hash("from",percentage,"to",position,"time",2,"easetype",iTween.EaseType.easeInOutCubic,"onupdate","SlidePercentage"));    
     }
     
     void SlidePercentage(float p){
         percentage=p;
     }
 }
 

A mouse Up event happens to switch Cameras, but doesn't seem to work

 using UnityEngine;
 using System.Collections;
 
 public class MouseUp : MonoBehaviour {
 
     
     public Camera oldCamera;
     public Camera newCamera;
     
 
     void OnMouseUp()
     {
         oldCamera.camera.active = false;
         newCamera.camera.active = true;
         }
 
 }
 

Any help is greatly appreciated

Thanks
