I`m not able to jump

Hi everyone. I followed this YouTube tutorial (link text) to get touch inputs for my game but for some reason I am not able to jump. Can anybody help me how to fix it?`enter code here`

using System.Collections; using System.Collections.Generic; using UnityEngine; public class MobileInput : MonoBehaviour {

 private const float DeadZone = 100.0f;

 public static MobileInput Instance { set; get; }

 private bool tap, swipeLeft, swipeRight, swipeUp;
 private Vector2 swipeDelta, startTouch;

 public bool Tap { get { return tap; }  }
 public Vector2 SwipeDelta { get { return swipeDelta; } }
 public bool SwipeLeft { get { return swipeLeft; } }
 public bool SwipeRight { get { return swipeRight; } }
 public bool SwipeUp { get { return swipeUp; } }


 private void Awake()
 {
     Instance = this;
 }

 private void Update()
 {
     // Reseting booleans
     tap = swipeLeft = swipeRight = swipeUp = false;

     // Input

     if (Input.touches.Length != 0)
     {
         if (Input.touches[0].phase == TouchPhase.Began)
         {

             tap = true;
             startTouch = Input.mousePosition;
     }
     else if (Input.touches[0].phase == TouchPhase.Ended || Input.touches[0].phase == TouchPhase.Canceled)
     {
             startTouch = swipeDelta = Vector2.zero;
     }
 }

     // Calculate Distance
     swipeDelta = Vector2.zero;
     if (startTouch != Vector2.zero)
     {
         // Check with mobile
         if(Input.touches.Length != 0)
         {
             swipeDelta = Input.touches[0].position - startTouch;
         }
     }

     // Check if you are beyond the deadzone
     if (swipeDelta.magnitude > DeadZone)
     {
         // Confirmed Swipe
         float x = swipeDelta.x;
         float y = swipeDelta.y;

         if(Mathf.Abs(x) > Mathf.Abs(y))
         {
             // Left or Right
             if (x < 0)
                 swipeLeft = true;
             else
                 swipeRight = true;
         }
         else
         {
             //Up or Down
             if (y > 0)
                 swipeUp = true;
         }

         startTouch = swipeDelta = Vector2.zero;
     }
 }

}

If that doesn´t help you I could also send my player controller script. You just need to ask. Thanks in advance!
