So The Fix To This Error CS1003

So One Of The Codes I Wasn't Going To Use, Gave Me This Error
error CS1003: Syntax error, '(' expected
Also With This One
error CS1026: ) expected

The Code
using System;
using StandardAssets.Characters.Common;
using UnityEngine.InputSystem;

public class FirstPersonInput : MonoBehaviour
{
InputAction StandardAssets.Characters.FirstPerson

/// <summary>
/// Implementation of the First Person input
/// </summary>
public class FirstPersonInput : CharacterInput
{
/// <summary>
/// Fired when the crouch is started
/// </summary>
public event Action crouchStarted;

/// <summary>
/// Fired when the crouch is ended
/// </summary>
public event Action crouchEnded;

// Tracks whether the character is crouching or not
bool m_IsCrouching;

/// <summary>
/// Resets the input states
/// </summary>
/// <remarks>used by the <see cref="StandardAssets.Characters.FirstPerson.FirstPersonBrain"/> to reset inputs when entering the walking state</remarks>
public void ResetInputs()
{
m_IsCrouching = false;
isSprinting = false;
}

/// <summary>
/// Handles the sprint input
/// </summary>
/// <param name="context">context is required by the performed event</param>
public override void OnSprint(InputAction.CallbackContext context)
{
base.OnSprint(context);
m_IsCrouching = false;
}

/// <summary>
/// Handles the crouch input
/// </summary>
/// <param name="context">context is required by the performed event</param>
public override void OnCrouch(InputAction.CallbackContext context)
{
BroadcastInputAction(ref m_IsCrouching, crouchStarted, crouchEnded);
isSprinting = false;
}

}
}

 

Your errors have line numbers. They will take you directly to the source of the error.

 

I'm New to Unity The Problem Is 7,54


Line 7 InputAction StandardAssets.Characters.FirstPerson


Line 54 isSprinting = false;
