Issue regarding triggers?

using UnityEngine;
using System.Collections;

public class manwalk : MonoBehaviour {

float walkSpeed = 90f;
float forwardSpeed = 0.5f;	
bool didwalk =false;
Animator animator;
bool dead  =  false;


// Use this for initialization
void Start () {
	animator = transform.GetComponentInChildren<Animator>();
	
	if(animator == null){
		Debug.LogError("Didn't find the animator");
	}
	
}
//Do grphics here
void Update () {
	if (Input.GetKeyDown(KeyCode.Space) || Input.GetMouseButtonDown(0)){
		didwalk =true;
	}
}

// do physics here
void FixedUpdate () {
	if(dead)
		return;
	
	rigidbody2D.AddForce(Vector2.right * forwardSpeed);
	if(didwalk ){
		rigidbody2D.AddForce(Vector2.up * walkSpeed);
		animator.SetTrigger("Dowalk");
		didwalk  =false;
	}

}
void OnCollisionEnter2D(Collision2D collision){
	animator.SetTrigger("Death");
	dead = true;
}

}

I am updating my script thanks to @Graham Dunnett for pin pointing the mistake. thanks a lot sir.
