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 : http://gyazo.com/ff871c69c54dd37e8d183ba3db63bcdf

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");
     Destroy(gameObject);
     }
  }
