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);
 
     }

Make a static variable at the Player class.

public static float speed;

And then:

public void SensitivityControl (float sensitivityControl){
          Player.speed = sensitivityControl;
}
