Why does only the first entry animation run???

Hi! I am kind of new to using unity 3d. I am making a 2d game. I have 3 animation clips: Idle, Run, and Jump. But only the entry animation runs. It keeps running and does not change to the others.. I think it does not recognize the float number(0.1) & trigger words (speed, Jump). Here's my script. (C#) [Thanks in advance!!]

using UnityEngine; using System.Collections;

public class t_scr : MonoBehaviour {

 private Animator anim;
 private Rigidbody2D rig2d;
 private float h;
 
 public float moveForce = 100f;
 public float maxSpeed = 2f;
 public float jumpForce = 100f;
 
 private bool facingRight = true;
 private bool grounded = false;
 private bool jump = false;


 // Use this for initialization
 void Start () {

     anim = GetComponent<Animator> ();
     rig2d = GetComponent<Rigidbody2D> ();
 
 }
 
 // Update is called once per frame
 void Update () {

     h = Input.GetAxis ("Horizontal");
     

     
     if(Input.GetKey(KeyCode.Space) && grounded) 
         
     {
         
         jump = true;
         
     
         
     }
 

     

 }

 void FixedUpdate()
 {
     anim.SetFloat ("Speed", Mathf.Abs (h));
     
     if (h * rig2d.velocity.x < maxSpeed) {
         rig2d.AddForce (Vector2.right * h * moveForce);
         
     }
     
     if (Mathf.Abs (rig2d.velocity.x) > maxSpeed) {
         
         rig2d.velocity = new Vector2 (Mathf.Sign (rig2d.velocity.x) * maxSpeed, rig2d.velocity.y);
     }
     
     if (jump) {
         jump = false;
         anim.SetTrigger ("Jump");
         rig2d.AddForce (new Vector2 (0f, jumpForce));
     }
     

     if(h>0 && !facingRight) {Flip();}
     else if(h<0 && facingRight) {Flip();}
     
 }
 
 void Flip ()
 {
     facingRight = !facingRight;
     
     Vector3 theScale = transform.localScale;
     theScale.x *= -1;
     transform.localScale=theScale;
 }

void OnCollisionEnter2D(Collision2D coll) {

     if (coll.gameObject.tag == "Earth") {

         grounded = true;
     }

     if (coll.gameObject.tag == "Oni") {
     

         StartCoroutine("TheEnd");
     }
     
 
         if (coll.gameObject.tag == "Book") {
     
     
             Destroy (coll.gameObject);
     
         }

     }

 IEnumerator TheEnd(){

     rig2d.AddForce (new Vector2 (0f, 700f));
     //GetComponent<BoxCollider2D> ().isTrigger = true;
     yield return new WaitForSeconds (1.0f);
     Application.LoadLevel ("Realscene");
 }
