Help, I need to make my game paddle move up & down (noob)

I have a script that I am trying to use to change the y-axis so I can move my game paddle up and down (trying to make a 3d ping pong) and idk what is wrong with my script here is the script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Paddle_2_controller : MonoBehaviour {

public float speed;

private Rigidbody rb;

void Start () {
rb = GetComponent ();

}

void FixedUpdate () {
float moveVertical = Input.GetAxis (“Vertical”);

Vector3 movement = new Vector3 (0.0f, 0.0f, moveVertical);

rb.AddForce (movement * speed);
}
}

Looks like you are setting Z axis value in movement.

How would I change Y axis?

to change the Y Axis:
Vector3 movement = new Vector3 (0.0f, moveVertical, 0.0f);

in general (I think…)
new Vector3 (Xaxis, Yaxis, Zaxis);

Ok I moved moveVertical but it isn’t moving at all
