Implicit downcast from 'Object[]' to 'UnityEngine.GUITexture[]'

Hi, i am very noob in Unity and in programming. I try to follow some tutorials but in one point of the track i get stuck with this error:
Implicit downcast from ‘Object’ to ‘UnityEngine.GUITexture’.
InvalidCastException: Cannot cast from source type to destination type.
Showlives…ctor () (at Assets/Juego Shooter/Scripts/Showlives.js:4)

I see that the problem is in the line 4 of my code but i don´t know what are wrong.

#pragma strict

var livetexture:Texture;//La textura que corresponde a las vidas restantes
var lives:GUITexture[]=[null,null,null];//el numero de vidas
var texto:GUIText;//El texto que indica fin de juego
var texto2:GUIText;//El texto que indica las instrucciones

function Update () {
	
	if(Globals.Lives==3)
	{
	lives[2].color.a=128;
	lives[1].color.a=128;
	lives[0].color.a=128;
	}
	
	if(Globals.Lives==2)
	{
	lives[2].color.a=0;
	lives[1].color.a=128;
	lives[0].color.a=128;
	}	

	if(Globals.Lives==1)
	{
	lives[2].color.a=0;
	lives[1].color.a=0;
	lives[0].color.a=128;
	}

	if(Globals.Lives==0)
	{//cuando el numero de vidas llega a 0, se muestra pantalla Game Over y si pulsamos boton asignado vamos a menu principal
	lives[2].color.a=0;
	lives[1].color.a=0;
	lives[0].color.a=0;
	texto.text="Game Over";
	texto2.text="Pulsa ESPACIO para Continuar";
		if(Input.GetButtonDown("Jump"))
		{
		Globals.Levels=0;
		Application.LoadLevel(Globals.Levels);
		}	
	}
}

Since null does not have a type, Unityscript can’t infer the type of your array literal. To make Unityscript infer the type, you can explicitly state the type of null reference:

var lives:Type[] = [null as Type];

For more simplicity, you can simply cast the entire stay to the type of array you need:

var lives:Type[] = [null] as Type [];

But since you are just making a bunch of null reference, which are the default value for reference type arrays, you can simply make a new stay:

var lives:Type[] = new Type[3];
