i get errors but i have no idea why

i get erreers such as these:

Assets/Scripts/Crafting/Building/CampfireBuild.js(38,105): UCE0001: ';' expected. Insert a semicolon at the end.

Assets/Scripts/Crafting/Building/CampfireBuild.js(38,104): BCE0043: Unexpected token: ,.

here is my script:

 #pragma strict
 
 var campfirePrefab : Transform;
 var player : GameObject;
 
 private var canBuild : boolean = true;
 
 function start()
 {
     renderer.material.color = Color.green;
     renderer.material.color.a = 0.5;
 }
 
 function OnTriggerEnter(col : Collider)
 {
     if(col.gameObject.tag == "Terrain" ||  col.gameObject.tag == "Tree")
     {
         renderer.material.color = Color.red;
         renderer.material.color.a = 0.5;
         canBuild = false;
     }    
 }
 
 function OnTriggerExit(col : Collider)
 {
     if(col.gameObject.tag == "Terrain" ||  col.gameObject.tag == "Tree")
     {
         renderer.material.color = Color.green;
         renderer.material.color.a = 0.5;
         canBuild = true;
     }    
 }
 
 function update()
 {
     if(Input.GetKeyDown("b") && canBuild == true)
     {
         Instantiate(campfirePrefab, player.transform.position + player.transform.forward * 2.0),Quaternion.Euler(270,200,200);
         player.GetComponent(Crafting).campFire.SetActive(false);
     }
 }
