c# - Control animation using animator control class

I did a sample existing code to control animation using animation.I dragged and dropped a character into the scene then I added a Animator to it and added the animator controller.Below I have given the screen short of the animation

Then I have attached the following code to it

Animator animator;

int eatHash=Animator.StringToHash("ideal");

int stateHash=Animator.StringToHash("Base Layer.pickbothfork");

void Start () {
    animator = GetComponent();

}

// Update is called once per frame
void Update () {
    //animator.SetBool ("isEat", true);
    float move = Input.GetAxis ("Vertical");
    animator.SetFloat ("Speed",move);

    AnimatorStateInfo stateinfo = animator.GetCurrentAnimatorStateInfo (0);
    if (Input.GetKeyDown(KeyCode.Space))

    {
        Debug.Log ("clicked spacebar");
        animator.SetTrigger(eatHash);
    }
}

The problem here is the above code is working,when I run the project the animation is getting played one after the another according to the state diagram.But when I click on the space bar the trigger function(jump animation ) is not working

if (Input.GetKeyDown(KeyCode.Space))
{
    Debug.Log ("clicked spacebar");

    animator.SetTrigger(eatHash);
}

Can anybody please help me finding solution for it
