How do I get my game to generate a random number for each counter,how do I make my game generate 2 different numbers at the same time

How do I make my game generate 2 different numbers on the counters? I can get 1 counter to work but on the other one stays at zero even when I attach it to the script itself. Do I have to make a separate code for the other counter? here's my code so far

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;

public class UiController : MonoBehaviour { public Text CountersText;

 private int counter;
  
  
 
  
  
 void Start()
 {
     counter = 0;
 
 }


 // Update is called once per frame
 void Update()
 {
     
 }

public void OnQuitButtonClick()

 {
     Application.Quit();
  
 }

public void OnRollButtonClick() { int roll = Random.Range(1,14); counter=roll; CountersText.text = counter.ToString();

 }

}
