Error code CS0246

Question

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.EventSystems;
 
 public class ButtonControl : IPointerEnterHandler, IPointerExitHandler 
 {
     private GameObject childText = null; //  or make public and drag
     void Start(){
         Text text= GetComponentInChildren<Text>();
         if (text != null) 
         {
             childText = text.gameObject;
             childText.SetActive(false);
         }
     }
     public void OnPointerEnter(EventSystems.PointerEventData eventData)
     {
         childText.SetActive(true);
     }
     public void OnPointerExit(EventSystems.PointerEventData eventData)
     {
         childText.SetActive(false);
     }
 }

im using this script so that when i highlight the button it shows some text, but i keep getting error code CS0246. It says that 'EventSystems' could not be found and asks if im missing an assembly reference. i have searched this up but couldnt find anything that helped. they are mostly other scripts that dont relate to my game.

Remove EventSystems from the function argument types:

 public void OnPointerEnter(PointerEventData eventData)
 {
     childText.SetActive(true);
 }
 public void OnPointerExit(PointerEventData eventData)
 {
     childText.SetActive(false);
 }

i fixed it up and then i got some more errors. if fixed them and then i got this: Assets/Shake.cs(13,48): error CS1525: Unexpected symbol `)'

i currently have this script: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.EventSystems; using UnityEngine.UI;

 public class Shake : MonoBehaviour {
 
     public class ButtonControl : IPointerEnterHandler, IPointerExitHandler 
     {
         private GameObject childText = null; //  or make public and drag
         void Start(){
             Text text= GetComponentInChildren<"Text(3)">();
             if (text != null) 
             {
                 childText = text.gameObject;
                 childText.SetActive(false);
             }
         }
         public void OnPointerEnter(PointerEventData eventData)
         {
             childText.SetActive(true);
         }
         public void OnPointerExit(PointerEventData eventData)
         {
             childText.SetActive(false);
         }
     }
 }

i got rid of the problem but then i got another one, and if these problems continue, i will end up with nothing. PLEASE HELP!!! Thanks. :)

Check in your scene if you have an object EventSystem with script attached EventSystem. It requires to be in order to work with uGUI.

right now it says that there is an unexpected symbol (error code CS1525) and that is ')'. the code looks fine.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.EventSystems;
 using UnityEngine.UI;
 
 public class Shake : $$anonymous$$onoBehaviour {
 
     public class ButtonControl : IPointerEnterHandler, IPointerExitHandler 
     {
         private GameObject childText = null; //  or make public and drag
         void Start(){
             Text text= GetComponentInChildren<"Text(3)">();
             if (text != null) 
             {
                 childText = text.gameObject;
                 childText.SetActive(false);
             }
         }
         public void OnPointerEnter(PointerEventData eventData)
         {
             childText.SetActive(true);
         }
         public void OnPointerExit(PointerEventData eventData)
         {
             childText.SetActive(false);
         }
     }
 }
