Beginner game dev here "No overload for method 'Move' takes 3 arguments"

I'm following a brackeys tutorial, and about halfway through the video we make it to this point
and I get "No overload for method 'Move' takes 3 arguments," I check the video and he doesn't get this error.
I'm not sure what to do.
Video Here:

Code here:

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

public class movement : MonoBehaviour
{
public CharacterController controller;
float horizontalmove = 0f;
public float runSpeed = 40f;

void Start()
{

}

void Update()
{
horizontalmove = Input.GetAxisRaw("Horizontal") * runSpeed;
}

void FixedUpdate()
{
controller.Move(horizontalmove * Time.fixedDeltaTime, false, false);
}
}

 

Please use code tags to make your code easy to read in your posts.

In the video, his controller variable is of type CharacterController2D. You've got CharacterController as the type of yours.

 

ohhh got it working thanks so much!
