if else statement for buttons.

hello all, tried figuring this out myself but sadly I cant.

for my project I’m making a leap motion lightsaber game. Got all the leap motion working, I can pick up my lightsaber and press buttons. However I need my button to transform the blade object to scale to look like its going up an down.
Now ive recently managed this with pressing a number key on the keyboard.

using UnityEngine;
using System.Collections;

public class saberScript2 : MonoBehaviour {

private GameObject blade;
private Light saberLight; 
public float maxLightIntensity = 3f;

private bool saberOn = false;
private float saberWidth;

// Use this for initialization
void Start () {
	blade = this.transform.Find ("blade").gameObject; //finds its child with name "blade" and assign it.
	saberLight = GetComponentInChildren<Light> (); //finds its child of light and assign it.
}

// Update is called once per frame
void Update () {
	/////////////////////////////////////////////////
	/// "vibrating" effect of lightsaber
	blade.transform.localScale -= new Vector3(Time.deltaTime * 3f,0,Time.deltaTime * 3f);
	if (blade.transform.localScale.x < 1.0f) {
		blade.transform.localScale += new Vector3(0.15f,0,0.15f);
	}
	/////////////////////////////////////////////////

	/////////////////////////////////////////////////
	/// turn lightsaber off and on. the intensity of the light goes with the length
	if (Input.GetKeyDown (KeyCode.Alpha1)) {
		if (saberOn)
			saberOn = false;
		else
			saberOn = true;
	}
	if (saberOn) { //extend the blade, turn on the light
		blade.transform.localScale = Vector3.Lerp(blade.transform.localScale, new Vector3(1,1,1), Time.deltaTime * 10f);
		if (saberLight.intensity < maxLightIntensity)
			saberLight.intensity = blade.transform.localScale.y * maxLightIntensity;
	} else { //diminish the blade, turn off the light
		blade.transform.localScale = Vector3.Lerp(blade.transform.localScale, new Vector3(1,0,1), Time.deltaTime * 10f);
		saberLight.intensity = blade.transform.localScale.y * maxLightIntensity;
	}
	////////////////////////////////////////////////

}

}

however I’m trying to get this to work for a button, which I cant. I can get the button to do one function which is make the blade go down. as follows.

using UnityEngine;
using System.Collections;

public class saberScript2 : MonoBehaviour {

private GameObject blade;
private Light saberLight; 
public float maxLightIntensity = 3f;

private bool saberOn = false;
private float saberWidth;

// Use this for initialization
void Start () {
	blade = this.transform.Find ("blade").gameObject; //finds its child with name "blade" and assign it.
	saberLight = GetComponentInChildren<Light> (); //finds its child of light and assign it.
}

// Update is called once per frame
public void Button_Click() { 

		blade.transform.localScale = Vector3.Lerp(blade.transform.localScale, new Vector3(0,0,0), Time.deltaTime * 20f);
		saberLight.intensity = blade.transform.localScale.y * maxLightIntensity;
	
    ////////////////////////////////////////////////

    Debug.Log("LightsaberDeactiavated");
}

}

the question is once that button is pressed and the scale of the object has gone small to the point it looks down, if I was to press the button again the object for re scale making it look like its going up again. Been on this all night and I’m starting to go insane. I have a feeling its something simply but cant manage to figure it out. Any help would be great thanks.

fixed it before anyone tries to comment. Simply fixed it by including a counter within the if statement. If anyone is stuck here is the code that works for my button.

using UnityEngine;
using System.Collections;

public class saberScript2 : MonoBehaviour
{

private GameObject blade;
private Light saberLight;
public float maxLightIntensity = 3f;

private bool saberOn = true;
public float Counter = 0;
public AudioSource SaberOn;
public AudioSource SaberOff;

private float saberWidth;

// Use this for initialization
void Start()
{
    blade = this.transform.Find("blade").gameObject; //finds its child with name "blade" and assign it.
    saberLight = GetComponentInChildren<Light>(); //finds its child of light and assign it.
}

// Update is called once per frame
public void Button_Click()
{
    if (Counter == 0)
    {
        blade.transform.localScale = Vector3.Lerp(blade.transform.localScale, new Vector3(0, 0, 0), Time.deltaTime * 30f);
        saberLight.intensity = blade.transform.localScale.y * maxLightIntensity;
        saberOn = false;
        SaberOff.Play();

        ////////////////////////////////////////////////

        Debug.Log("LightsaberDeactiavated");
    }

    if (Counter == 1)
    {
        blade.transform.localScale = Vector3.Lerp(blade.transform.localScale, new Vector3(1, 1,1), Time.deltaTime * 30f);
        saberLight.intensity = blade.transform.localScale.y * maxLightIntensity;
        saberOn = true;
        SaberOn.Play();

        ////////////////////////////////////////////////

        Debug.Log("LightsaberActiavated");
    }
    Counter++;

    if (Counter == 2)
    {
        Counter = 0;
    }
    Debug.Log("LightsaberDeactiavated");
}

pretty basic answer, something I learned two years ago ahaha.
