Bleeding and Health Generation Skript

Hey guys :) Im currently working on an FPS project and I created this fairly simple skript for Health generation, with the mechanic that the player can bleed out if he looses too much health. I get a compound error from unity saying this: 'js(43,1): BCE0044: expecting }, found ''.

I was wondering if you could help me out sorry if I made some simple mistakes im still learning :D

 #pragma strict
 var MaxHealth = 80.0;
 
 var health = MaxHealth;
 
 //Time Till the Player starts to Regenerate after timer Trigger
 var regenTime = 100.0;
 //How fast the Player Regenerates
 var regenSpeed = 1.0;
 
 //Time till the player starts to Bleed after timer Trigger
 var bleedTime = 10.0;
 //How fast the Player Bleeds
 var bleedSpeed = -1.0;
 
 //Timer for Regeneration/Bleeding
 private var timer = 0.0;
 
 function Start () {
 
 }
 
 function Update () 
 {
     if(health<=0)
         die();
         
     if(health<=21){
         if(timer<regenTime) {
             timer+=0.1;
         }else{
             health += regenSpeed/10;
         }
     
     if(health>=20){
         if(timer<bleedTime) {
             timer+=0.1;
         }else{
             health -= bleedSpeed/20;
         }
     }
 }
