FindGameObjectsWithTag() script not working right.

Questions & Answers

I want there to be a button in the game to destroy all instances of a certain coloured cube when pressed but when I use ‘FindGameObjectsWithTag()’ to try and do that it doesn’t work properly, if I press the button it will destroy any cubes that were in the game before i ran it but not any I create in the game and will only destroy red cubes (as opposed to the blue and green cubes). This is my script;

var Projectile1 : Rigidbody;
var Projectile2 : Rigidbody;
var Projectile3 : Rigidbody;
var SpawnObject : Transform;

var Speed = 30;
var FireType = 0;
var UnlockLevel : int;

function Start () {
	var UnlockLevel = 0;
	var redCube : GameObject[];
	var blueCube : GameObject[];
	var greenCube : GameObject[];
}

function Update () {
	if(Input.GetButtonDown("Fire1")&&!Input.GetButtonDown("Fire2")&&UnlockLevel == 1) {
		var clone : Rigidbody;
		if(FireType == 0) {
			clone = Instantiate(Projectile1, SpawnObject.position, SpawnObject.rotation);
		}
		if(FireType == 1) {
			clone = Instantiate(Projectile2, SpawnObject.position, SpawnObject.rotation);
		}
		if(FireType == 2) {
			clone = Instantiate(Projectile3, SpawnObject.position, SpawnObject.rotation);
		}
		clone.velocity = transform.TransformDirection(Vector3.up * Speed);
	}
	if(Input.GetButtonDown("Fire2")&&!Input.GetButtonDown("Fire1")) {
		var clone2 : Rigidbody;
		if(FireType == 0) {
			clone = Instantiate(Projectile1, SpawnObject.position, SpawnObject.rotation);
		}
		if(FireType == 1) {
			clone = Instantiate(Projectile2, SpawnObject.position, SpawnObject.rotation);
		}
		if(FireType == 2) {
			clone = Instantiate(Projectile3, SpawnObject.position, SpawnObject.rotation);
		}
	}
	if(Input.GetButtonDown("FireChange")) {
		if(FireType <= 1) {
			FireType += 1;
		} else {
			FireType = 0;
		}
	}
	if(Input.GetKeyDown("Destroy")) {
		if(FireType==0) {
			redCube = GameObject.FindGameObjectsWithTag("RedCube");
			for(var i : int=0; i<redCube.Length; i++) {
				Destroy(redCube*);*

  •  	}*

  •  }*

  •  if(FireType==1) {*

  •  	blueCube = GameObject.FindGameObjectsWithTag("BlueCube");*

  •  	for(var j :int=0; i<blueCube.Length; i++) {*

_ Destroy(blueCube*);_
_ }_
_ }_
_ if(FireType==2) {_
_ greenCube = GameObject.FindGameObjectsWithTag(“GreenCube”);_
_ for(var k : int=0; i<greenCube.Length; i++) {_
_ Destroy(greenCube);
 }
 }
 }
}*
What am I doing wrong?_

Figured out how to fix it. Needed to use;
Input.GetButtonDown(“Destroy”)
Instead of;
Input.GetKeyDown(“Destroy”)
