C# code throwing error for FrognLog tutorial.

Hey all,

I'm new and have never worked in C#. I'm as far as adding as a playerMovement script to my player(Frong). But when I press play it throws 2 errors saying:

!(in a yellow triangle) Parameter 'speed' does not exist. UnityEngine.Animator:SetFloat(String, Single) and !(in red stop sign) ArgumentException: Input Axis vertical is not set up.

To Change the input settings use: Edit -> Project Settings -> Input

My code is:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class PlayerMovement : MonoBehaviour {

private Animator playerAnimator;
private float moveHorizontal;
private float moveVertical;
private Vector3 movement;

// Use this for initialization
void Start() {
    playerAnimator = GetComponent<Animator>();

}

// Update is called once per frame
void Update() {
    moveHorizontal = Input.GetAxisRaw ("Horizontal");
    moveVertical = Input.GetAxisRaw ("vertial");

    movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
}

void FixedUpdate() {
    if (movement != Vector3.zero) {
        playerAnimator.SetFloat("speed", 3f);
    } else {
        playerAnimator.SetFloat("speed", 0f);

    }
}

}

The Frog is a prefab that I downloaded and I'm editing it for this tutorial. The code written matches the tutorial video. I'm just not sure what and how i should fix this issue. Do I add another Component to the player which triggers Vertical axis?
