The name '' does not denote a valid type ('not found').

I cant fix this error, and im new to scripting and coding in general, so if you could treat me like i am a complete idiot(Which i wouldn’t deny in the field of coding)that be great.
THE ERROR- Assets/DamageTrigger.js(6,20): BCE0018: The name ‘Widget_Status’ does not denote a valid type (‘not found’).

//DamageTrigger.js: A simple, variable damage trigger that can be
//applied to any kind of object.
//Change the damage amount in the Inspector.

var damage: float = 20.0;
var playerStatus : Widget_Status;

function OnTriggerEnter(){
    playerStatus = GameObject.FindWithTag("Player");
@script AddComponentMenu("Environment Props/DamageTrigger")

Either you have no script called Widget_Status in your project, or else it’s in C# and you don’t have script compilation order set up correctly.
