Insert Semicolon error

When i make a script some times it says insert a semicolon but there already is a semi colon on the line it tells me to put it on so can someone help me out with this problem?

here is the code:

 #pragma strict
 
 public var objectToSpawn : GameObject;
 
 public var horizontalOffset : float = 10.0f;
 
 public var minVerticalOffset : float = 0.0f;
 
 public var maxVerticalOffset : float = 3.0f;
 
 public var minTimeBetweenSpawns : float = 1.0f;
 
 public var maxTimeBetweenSpawns : float = 5.0f;
 
 private var spawnTimer : float = 0.0f;
 
 private var spawnTime : float = 0.0f;
 
 
 
 
 function Start () 
 
 {
 
 spawnTime = minTimeBetweenSpawns + Random.value*(maxTimeBetweenSpawns - minTimeBetweenSpawns);
 
 }
 
 function Update () 
 
 {
 
 spawnTimer += Time.deltaTime;
 
     if(spawnTimer >= spawnTime)
     {
         Vector3 spawnPosition = Camera.main.transform.position;
         spawnPosition.x += horizontalOffset;
         spawnPosition.y = minVerticalOffset + Random.Value*(maxVerticalOffset - minVerticalOffset);
         spawnPosition.z = 0;
         
         //Spawn our Object
         Instantiate(objectToSpawn, spawnPostition, objectToSpawn.transform.rotation);
         
         //Reset Timer and Time
         spawnTimer = 0.0f;
         spawnTime = minTimeBetweenSpawns + Random.value*(maxTimeBetweenSpawns - minTimeBetweenSpawns);
     }
 }
