HELP NO MOVEMENT

super new to this but ive done everything exactly how its done in the intro videos till near the end of vedio three but i cant get the sphere to move when i play no error messages or anthing just no move my script is as follows

using UnityEngine;

using System.Collections;

public class PlayerController : MonoBehaviour
{
void fixedupdate ()
{
	float moveHorizontal = Input.GetAxis("Horizontal");
	float moveVertical = Input.GetAxis("Vertical");
	
	Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

	rigidbody.AddForce(movement);
}

}

You did not exactly do like in the video, your FixedUpdate is not written the same.

You have fixedupdate when it should be FixedUpdate. Cap letters matter.
