Error CS1003 Syntax error "{" expected

I wrote this code before and didn't get this error.
Here is the code :

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

public class PlayerMovement : MonoBehaviour
{
public CharacterController controller;

public float speed = 12f;
public float gravity = -9.81f;
public float jumpHeight = 3;

public Transform groundCheck;
public float groundDistance = 0.4f;
public LayerMask groundMask;

Vector3 velocity;
bool isGrounded;

// Update is called once per frame
void Update()
{

isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);

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

float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");

Vector3 move = transform.right * x + transform.forward * z;

if (Input.GetButtonDown("Jump") && isGrounded) ;
{
velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
}

controller.Move(move * speed * Time.deltaTime);

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

Nvm found it out

 

found it out it was : ausing at the 1st line. btw thanks for replying

 

You also have a semicolon after this line which does not cause a syntax error but is most likely not wanted:

Code (CSharp):

1. if (Input.GetButtonDown("Jump") && isGrounded) ;

Due to this semicolon the following block is executed regardless of the if statement.
