Hello
I would like to know why the scripts I’m using are not working properly with my timer i would really appreciate any help !

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

public class Timertext : MonoBehaviour
{
	public float timeLeft;
	public GUIText Timer;
	public GUIText gameOverText;

public void Update()
{
	timeLeft -= Time.deltaTime;
	if (timeLeft <= 0.0f) {
		Timer.text = "You ran out of time";
		gameOverText.text = "GAME OVER";
	} 
	else
	{
		Timer.text = "Time left = " + (int)timeLeft +  " seconds";
	}
	}
}

using UnityEngine;
using System.Collections;

public class Tanktimer : MonoBehaviour {

	public Timertext Timertext;
	
	// Update is called once per frame
	void Update () {
	
	}
	void OnTriggerEnter(Collider other)
	{
		if(other.gameObject.tag == "PickUp")
		{
			//add time
			//Destroy(other.gameObject);
			Timertext.timeLeft += 10;  
        }
	}
}

public Timertext Timertext; //BAD - Dont name a variable to be the same as its Type
Try

public Timertext timerText;

Then change

timerText.timeLeft += 10;

If you are trying to access a particular script rather than the instance in your script, you will need to reference the gameobject containing the script and use GetComponent to modify the information.
