a 'phantom' error.

in this script i have,

 var opensavingthrow : int = 1;
 var hacksavingthrow : int = 1;
 
 var amiaHACKdoor : boolean = false;
 
 var playerholder : GameObject;
 var player : player_script;
 
 function OnTriggerEnter (other : Collider) {
         if(amiaHACKdoor == true){
             if(other.GetComponent(player_script).Hackskill >= hacksavingthrow){
             DestroyObject (gameObject);
             player.pointtext.text = "-door hacked open.";
             }
             else if(other.GetComponent(player_script).Openskill < opensavingthrow){{
             player.pointtext.text = "-Hack skill required:"+hacksavingthrow;
             }
         }
         else if(amiaHACKdoor == false){
             if(other.GetComponent(player_script).Openskill >= opensavingthrow){
             DestroyObject (gameObject);
             player.pointtext.text = "-door picked open.";
             }
             else if(other.GetComponent(player_script).Openskill < opensavingthrow){{
             player.pointtext.text = "-Lockpick skill required:"+opensavingthrow;
             }
     
     
     }
 }
 
 function Start(){
 
 playerholder = GameObject.FindGameObjectWithTag("Player");
 player = playerholder.GetComponent(player_script);
 
 }

but comes up with the error,

Assets/scripts/skilltest.js(16,47): BCE0044: expecting :, found '='.

but at that line,

             player.pointtext.text = "-Hack skill required:"+hacksavingthrow;

there is no equals sign at that point, the error message says it's in the middle of the word skill, in the string. I tried copying the script, deleting it, making a new script, and pasting it in, but that didn't work.

Any ideas?
