I am making a 2d game and I was doing pretty good. However, I was making a script for my sprites texture to flip when I press A and D. This is my entire script and a list of my errors if it will help.

pragma strict

var X : float;

function Start () {

 X = transform.localScale.x;

}

function Update () { if(Input.GetKey.("a")){

     transform.localScale.x = X;
 }else if(Input.GetKey.("d")){
 
     transform.localScale.x = -X;
 }
 

}
