error CS0103: The name 'velocity' does not exist in the curr

I got the this error 3 times and needed to know what was going on, what am I doing wrong in this script:

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

public class playermovement : MonoBehaviour
{
    [SerializeField] private float moveSpeed;
    [SerializeField] private float walkSpeed;
    [SerializeField] private float runSpeed;
    private Vector3 moveDirection;

    private CharacterController controller;
    private Vector3 veloctiy;

    [SerializeField] private bool isGrounded;
    [SerializeField] private float groundCheckDistance;
    [SerializeField] private LayerMask groundMask;
    [SerializeField] private float gravity;
 
    [SerializeField] private float jumpHeight;

    private void Start()
    {
        controller = GetComponent<CharacterController>();
    }

    private void Update()
    {
        Move();
    }

    private void Move()
    {
        isGrounded = Physics.CheckSphere(transform.position, groundCheckDistance, groundMask);

        if(isGrounded && veloctiy.y < 0)
        {
            veloctiy.y = -2f;
        }

        float moveZ = Input.GetAxis("Vertical");

        moveDirection = new Vector3(0, 0, moveZ);

        if(isGrounded)
        {
            if(moveDirection != Vector3.zero && !Input.GetKey(KeyCode.LeftShift))
            {
                Walk();
            }
            else if(moveDirection != Vector3.zero && Input.GetKey(KeyCode.LeftShift))
            {
                Run();
            }
            else if(moveDirection == Vector3.zero)
            {
                Idle();
            }

            moveDirection *= moveSpeed;

            if(Input.GetKeyDown(KeyCode.Space))
            {
                Jump();
            }
        }

        controller.Move(moveDirection * Time.deltaTime);

        veloctiy.y += gravity * Time.deltaTime;
        controller.Move(velocity * Time.deltaTime);
    }

    private void Idle()
    {

    }

    private void Walk()
    {
        moveSpeed = walkSpeed;
    }

    private void Run()
    {
        moveSpeed = runSpeed;
    }
    private void Jump()
    {
        velocity.y = Mathf.Sqrt(jumpHeight * -2 * gravity);
    }
}

Hey, you might’ve already noticed but velocity is spelt wrong in a few places within your script. Hope that helps

what do you mean like where?

did you mean to spell is as ‘veloctiy’ on lines 13, 38 and 70

ok well I just fixed them, but now there is 4 errors, all the sa

ok but now they are saying that it doesn’t work in the context, STILL and there are 4

wait nvm
