3D Menu Help

I’m trying to make a 3D menu for a game I’m working on, I followed that tutorial 3D Menu Tutorial , But when I get to the part where I have to link my buttons to the MenuManager (drag the buttons to the array slots, it doesn’t work) the array I created on my script doesn’t show up on the Unity interface. Here are the codes im using:

function OnSelected(on:boolean)
{
if(on)
{
iTween.moveTo(gameObject, {“z”: -4, “time”:0.5, “transition”: “bounce”});
iTween.rotateTo(gameObject, { “y”: -90, “time”:0.5});
}
else
{
iTween.moveTo(gameObject, {“z”:0, “time”: 0.5, “transition”:“bounce”});
iTween.rotateTo(gameObject, {“y”: 0, “time”:0.5});
}
}

And that is my Menu Manager:

var menuItems:MenuItem[];

var currentMenuItem:int = 0;

var keyDelay:float = 0.25;

function Start()
{
menuItems[currentMenuItem].OnSelected(true);

	var lastMenuItem:int = currentMenuItem;
	
	while(true)
	{
		if(Input.GetAxisRaw("Vertical") > 0.9)
		{
			lastMenuItem = currentMenuItem;
			
			currentMenuItem--;
			if(currentMenuItem < 0) currentMenuItem = 0;
			
			if(lastMenuItem != currentMenuItem)
			{
				menuItems[lastMenuItem].OnSelected(false);
				
				menuItems[currentMenuItem].OnSelected(true);
			}
			
			yield new WaitForSeconds(keyDelay);
		
		}
		else if(Input.GetAxisRaw("Vertical") < -0.9)
		{
			lastMenuItem = currentMenuItem;
			
			currentMenuItem++;
			if(currentMenuItem >= menuItems.length) currentMenuItem = menuItems.length -1;
			
			if(lastMenuItem != currentMenuItem)
			{
				menuItems[lastMenuItem].OnSelected(false);
				
				menuItems[currentMenuItem].OnSelected(true);
			}
			
			yield new WaitForSeconds(keyDelay);
		}
		yield;
	
	if(Input.GetButtonDown("Jump"))
	{
		Debug.Log("voce ativou o botao" + currentMenuItem);
		menuItems[currentMenuItem].Activate();
	}
}

}

Solved, my script was looking for the OnSelected property on my MenuItem prefab instead of on the MenuItem script
