Sensitivity Slider

This is really frustrating! I have been working on this for a week and have not been able to make it work. I am trying to make a sensitivity slider so the player can adjust how quickly the character moves. I made a slider and speed variable (that is attached to my player script). The slider moves like it should and the handle value saves, but the speed remains the same. I cannot get the sensitivity to change. I know I am close, but I can't figure out what I need to add or what I could be doing wrong.

Debug is not showing any errors!

Here's my code:

Code 1:

 using UnityEngine;
 using System.Collections;
 using UnityEngine .Audio ;
 using UnityEngine .SceneManagement ;
  
  public class Player : MonoBehaviour {
  
  public float speed;
  
  void Update(){

     //speed = PlayerPrefs.GetFloat ("CurSens");

  if (!PausePanel.isPaused && Input.touchCount > 0 && Input.GetTouch (0).phase == TouchPhase.Moved) {
              
              Vector2 touchDeltaPosition = Input.GetTouch (0).deltaPosition;
              transform.Translate (touchDeltaPosition.x * speed, touchDeltaPosition.y * speed, 0);
  }
  
  if(!PausePanel.isPaused && mySpriteRenderer != null)
          {
              if(Input.GetTouch (0).deltaPosition .x<0)
              {
                  // flip the sprite
                  mySpriteRenderer.flipX = true;
              }
  
              if(Input.GetTouch (0).deltaPosition.x >0)
              {
                  // flip the sprite
                  mySpriteRenderer.flipX = false;
              }
                  
  
      }

Code 2:

  using UnityEngine;
  using System.Collections;
  using UnityEngine.SceneManagement;
  using UnityEngine.UI;
  
  public class PausePanel : MonoBehaviour {
  
  public Slider sensitivitySlider;
  
  void Start(){
  
  if (sensitivitySlider) {
  
              instance.speed = PlayerPrefs.GetFloat ("CurSens");
              sensitivitySlider.value = instance.speed;
  
          }
  
  instance = GameObject.Find("Biting Tyson Head").GetComponent <Player> ();
  
  }
  
  public void SensitivityControl (float sensitivityControl){
  
          instance.speed = sensitivityControl;
          PlayerPrefs.SetFloat ("CurSens", instance.speed);
  
      }
