Help destroying a seperate game object on collision enter

Hi I have a script that plays an audio clip once when I enter the collider. For one instance I want to destroy a game object in my scene that isn’t connected to the audio object.
The script so far:

using UnityEngine;
using System.Collections;

public class PlayAudioDESTROY : MonoBehaviour {
	private AudioSource audio;
	private bool hasPlayed = false;
	void Start () {
		audio = GetComponent <AudioSource>();


	void OnTriggerEnter(Collider other)
		if (audio.isPlaying == false && hasPlayed == false)
			hasPlayed = true;


I want to add code to this that allows me to drag a different game object onto this script in the inspector so when I walk through it, it destroys said game object. Anybody know how to do this?

many thanks.

create a public gameobject variable at the top. It will show up in the inspector for assignment. whatever you call it, call Destroy(saidGameObject) where you need it.
