I need help with an error

So I put a semicolon where it says to put it but for some reason the error stays even after I do clear errors so I know its not just a user error

Picture of errors in the console : Screenshot - ff871c69c54dd37e8d183ba3db63bcdf - Gyazo

here’s the script :

#pragma strict

import UnityEngine.UI;

var DamageValue = -1:
var gamemaster : GameObject;
var textobject : GameObject;
function OnTriggerEnter (info : Collider) 
	if (info.tag == "Player")
	textobject.GetComponent.<health>().Health = +DamageValue;
	textobject.GetComponent.<Text>().text = "Health: " +DamageValue;
	Debug.Log("-1 Health");

Fix bugs from top to bottom. Your line 5 ends in a colon instead of a semi-colon.
