Parsing Error(newObjRight)

So I was coding a multishot projectile in the form of a 2d missile. Ideally I want two missiles side by side to fire forward on the plane. I have not yet saved the code because I noticed there would be a parsing error (newObjRight and +=). I would like to know if anyone has any ideas on how to solve this. Also I believe the error is only in the Projectile2 script and not anywhere else. Thanks ahead of time!

 using UnityEngine;
 using System.Collections;
 
 public class Projectile2 : MonoBehaviour {
     
     // Used to control how fast the game object moves
     public float MoveSpeed = 7.0f;
     
     // Use this for initialization
     void Start () {
 
     }
     
     // Update is called once per frame
     void Update () {
         transform.position += 
             transform.up * Time.deltaTime * MoveSpeed;
         
     }
 
     public void FireMultiShotSideBySide();
     {
         //Right
         Projectile2 newObjRight = Instantiate (Projectile2, transform.position, transform.rotation) as Projectile2
         newObjRight.transform.position += newObjRight.transorm.right * 1.0f
 
         //Left
         Projectile2 newObjLeft = Instantiate (Projectile2, transform.position, transform.rotation) as Projectile2
         newObjLeft.transform.position += newObjLeft.transorm.left * 1.0f
     }
 }
