Dynamic RTS-style Text UI

Hey I'm trying to put text that can change depending on what you do onto the ui of a game that I'm making and for some reason the public variables for the text aren't going onto the inspector of the object that the script is attached to. Any idea why? I'm still new to coding

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UIElements;
5.  
6. public class ResourceManager : MonoBehaviour
7. {
8.    
9.     public float gold;
10.     public float maxGold;
11.     public float wood;
12.     public float maxWood;
13.     public float population;
14.     public float maxPopulation;
15.  
16.     public TextElement goldDisp;
17.     public TextElement woodDisp;
18.     public TextElement populationDisp;
19.  
20.     // Start is called before the first frame update
21.     void Start()
22.     {
23.        
24.     }
25.  
26.     // Update is called once per frame
27.     void Update()
28.     {
29.         goldDisp.text = "" + gold + "/" + maxGold;
30.  
31.         //if(gold >= maxGold)
32.         //{
33.         //    gold = maxGold;
34.         //}
35.     }
36. }

 

Docs say TextElement is an experimental API. Try Text instead.

 

Ok I tried that and it gave me this error

In case you are wondering, I've tried using .UI instead of .UIElements and after solution after solution .UI only worked in a 2017 unity version I had installed, the 2 2019 versions I have installed, both I've worked on with my game, seems to have taken out .UI and makes me use .UIElements

 

What happens if you add "using UnityEngine.UI;" to the top of your script?
