Splitscreen, double player touch follow finger working. But have a bug

Hi, After loads of hours of trying complex scripts. I have managed to get one realy simple to work. I use same script for both players, just different screen.width (><). And it works good. But if right player touches first it gets messy.. how if the scripts are totaly same? no matter what combination.

Here is my script:

using UnityEngine; using System.Collections;

public class TouchP1 : MonoBehaviour {

 void Update () {
     if (Input.touchCount == 1) {

         Touch touch = Input.GetTouch(0); 
         
         if (touch.position.x < Screen.width/2)
         {
             if (touch.phase == TouchPhase.Stationary || touch.phase == TouchPhase.Moved) {

                 Vector3 touchPosition = Camera.main.ScreenToWorldPoint(new Vector3(touch.position.x, touch.position.y, 10));                
                 transform.position = touchPosition ;

             }
         }
     }
     else if (Input.touchCount == 2) {

         Touch touch = Input.GetTouch(1); 
         
         if (touch.position.x < Screen.width/2)
         {
             if (touch.phase == TouchPhase.Stationary || touch.phase == TouchPhase.Moved) {

                 Vector3 touchPosition = Camera.main.ScreenToWorldPoint(new Vector3(touch.position.x, touch.position.y, 10));                
                 transform.position = touchPosition ;
             }
         }
     }
 }
