Why Can't I Fix This Error In My Script?

I keep getting the same error: “Assets/MeleeSystem.js(3,21): UCE0001: ‘;’ expected. Insert a semicolon at the end.”
How do I fix it?
This is the script I’m using:

#pragma strict

var TheDammage : int - 50;
var Distance : float;

function Update () 
{
	if (Input.GetButtonDown("Fire1"))
	{
		var hit : RaycastHit;
		if (Physics.Raycast (transform.position, transform.TransformDirection(Vector3.forward), hit))
		{
			Distance = hit.distance;
			hit.tranform.SendMessage("ApplyDammage", TheDammage, SendMessageOptions.DontRequireReceiver);
		}
	}
}

Line 3, I suspect you intended the - to be = as follows

#pragma strict

var TheDammage : int = 50;
var Distance : float;

// etc

On line 3, the minus sign should be an equals sign:

var TheDammage : int = 50;

You also left out the ‘s’ in ‘transform’ on line 14.
