How do you switch between cameras?

So what I've been trying to do is make it so that I'm able to switch between cameras so at a press of a button I see a different area. My problem is that I can't seem to make it so my script works. It currently just stays on enabled camera and doesn't change (also as a side note, I have the script on my character). I've checked google and from what I could tell this script should work.

here is my current script.

var Camera1: Camera; var Camera2: Camera;

function Start() { Camera1.enabled = false; Camera2.enabled = true; }

if (Input.GetKey("1")) { Camera1.enabled = true; Camera2.enabled = false; }

if (Input.GetKey("2")) { Camera1.enabled = false; Camera2.enabled = true; }

Thanks!
