make rawimage appear in trigger on button press help with code

SignText assigned to RawImage that has to appear
uiElement assigned to text telling player to press "e"
but when i enter the trigger nothing happens at all, im quite new at unity so sorry if i sound dumb.
and i do have FPScontroller in Players Tag.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ShowText_OnKeyPress : MonoBehaviour {
6.     [SerializeField] private GameObject SignText;
7.     [SerializeField] private GameObject uiElement;
8.  
9.     void OnTriggerStay(Collider other)
10.     {
11.         if (other.CompareTag ("Player"))
12.         {
13.             uiElement.SetActive (true);
14.  
15.             if (Input.GetKeyDown (KeyCode.E))
16.             {
17.                 SignText.SetActive(true);
18.                 uiElement.SetActive(false);
19.             }
20.  
21.         }
22.     }
23.  
24.     private void OnTriggerExit(Collider other)
25.     {
26.         if (other.CompareTag ("Player"))
27.         {
28.             uiElement.SetActive(false);
29.             SignText.SetActive(false);
30.         }
31.     }
32. }
33.  

 

Try using OnTriggerEnter instead of OnTriggerStay.

 

thanks for attention but still nothing. looking back at it i dont know what could be wrong with the script everything looks fine to me.
