Can't make my character to jump ??

Hey ! Got a little problem, all of my character's animations work, but only Jumping animation doesn't work. I'm working on mecanim. Here is a screen and the script, can you help me ? ^^

 using UnityEngine;
 using System.Collections;
 
 [DisallowMultipleComponent]
 [RequireComponent(typeof(Animator))]
 public class Movement : MonoBehaviour {
 
     Animator anim;
 
     void Awake(){
         anim = GetComponent<Animator> ();
     }
 
     void Update() {
         /*Turning isn't necessary because the turning method is in the CameraTurning script,
          *there's no movement within the character while turning. */
 
         Strafe();
 
         //Jumping
         Jump();
 
         //Walking
         Walking();
 
         //Moving
         Move();
     }
         
     void Jump() {
         if (Input.GetKey (KeyCode.Space)) {
             anim.SetBool ("Jumping", true);
         } else {
             anim.SetBool ("Jumping", false);
         }
     }
 
     void Walking() {
         if (Input.GetKey (KeyCode.LeftShift)) {
             anim.SetBool ("Walking", true);
         } else {
             anim.SetBool ("Walking", false);
         }
 
     }
 
     void Move() {
         anim.SetFloat ("Forward", Input.GetAxis("Vertical"));
     }
         
     void Strafe() {
 
         //Right Strafe Run
         if (Input.GetKey (KeyCode.E)) {
             anim.SetBool ("RightStrafeRun", true);
         } else {
             anim.SetBool ("RightStrafeRun", false);
         }
 
         //Right Strafe Walk
         if (Input.GetKey (KeyCode.E)) {
             anim.SetBool ("RightStrafeWalk", true);
         } else {
             anim.SetBool ("RightStrafeWalk", false);
         }
 
         //Left Strafe Run
         if (Input.GetKey (KeyCode.A)) {
             anim.SetBool ("LeftStrafeRun", true);
         } else {
             anim.SetBool ("LeftStrafeRun", false);
         }
 
         //Left Strafe Walk
         if (Input.GetKey (KeyCode.A)) {
             anim.SetBool ("LeftStrafeWalk", true);
         } else {
             anim.SetBool ("LeftStrafeWalk", false);
         }
 
 
     }
 
 }
