Assets/Shoot.js(7,90): BCE0044: expecting :, found ';'. whats wrong?

public var BulletPrefab : Transform; 
public var BullletSpeed : float = 6000; 

function Update () {
     if (Input.GetButtonDown("Fire1")) {
         if (!BulletPrefab || !BulletSpeed( {
            Debug.Log("[Shoot] 'BulletPrefab' or 'BulletSpeed' is undefined");  
        } else {    
             var BulletCreate = Instantiate(bulletPrefab, GameObject.Find("Spawnpoint").Transform.position, Quaternion.identity);
             BulletCreate.rigidbody.AddForce(Transform.forward * Bulletspeed);
        }    
    }  
} 

Look close at BulletSpeed( {

Change this:

GameObject.Find("Spawnpoint").Transform.position

to this:

GameObject.Find("Spawnpoint").transform.position
