Hi mazket! Are you trying to acces a **Script Component** named "Button" or an **GameObject**? **If Button is an object:** using UnityEngine; using System.Collections; public class Cooldown : MonoBehaviour { public GameObject used; // Use this for initialization void startCD () { StartCoroutine (SkillCD ()); } // Update is called once per frame IEnumerator SkillCD () { yield return new WaitForSeconds(10f); used = GameObject.FindGameObjectWithTag ("Used"); used.GetComponent ().interactable = true; used.tag = "Untagged"; } } **QUESTION 1:** Is "Button" an object or a script name? If it is an object, change the "Button" to the actual script name you are trying to access. Is "interactable" a private bool? If it is private, it won't be accessible! Switch to public! I think you are mixing some components... Bests, Math!
