zooming in and out

i have this code what works and zooms me in but how do i zoom out ?

private var baseFOV : float;

function Start () { baseFOV = camera.fieldOfView;

}

function Update () { if (Input.GetMouseButton(1)) camera.fieldOfView = 37; //add the Code for texture changing to Sniper Scope here else camera.fieldOfView = baseFOV; ? //add the code for texture changing to normal scope here

}

if (Input.GetMouseButton(2)) camera.fieldOfView = 60; //add the Code for texture changing to Sniper Scope here else camera.fieldOfView = baseFOV; ? //add the code for texture changing to normal scope here

add a boolean flag e.g. isSniper = false;

Check for flag when you press the sniper scope button if its true change it to false and change field of view to normal , if its false (it should be at the start) change it to true and change field of view to sniper mode.
