Help im getting this error Assets/MouseManager.cs(38,32): error CS1525: Unexpected symbol `grabbedObject'

using UnityEngine; using System.Collections;

public class MouseManager : MonoBehaviour {

 Rigidbody2D grabbedObject = null;
 
 Vector2 mousePos2D;

 float dragSpeed = 4f;

 void Update() {
     if( Input.GetMouseButtonDown (0)){
         Vector3 mouseWorldPos3D = Camera.main.ScreenToWorldPoint(Input.mousePosition);
         mousePos2D = new Vector2(mouseWorldPos3D.x, mouseWorldPos3D.y);
     }
     
     Vector2 dir = Vector2.zero;
     RaycastHit2D hit = Physics2D.Raycast (mousePos2D, dir);
     if(hit && hit.collider && hit.collider.GetComponent<Rigidbody2D>() != null) {
         hit.collider.GetComponent<Rigidbody2D>().gravityScale = 1;
     }

     if( Input.GetMouseButtonDown (0)){
         grabbedObject = null;
     }
 }

 void FixedUpdate() {
     if(grabbedObject != null) {
        Vector3 mouseWorldPos3D = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        mousePos2D = new Vector2(mouseWorldPos3D.x, mouseWorldPos3D.y);

        Vector2 dir = mousePos2D - grabbedObject.position;

        dir *= dragSpeed

        grabbedObject.velocity = dir;
     }
 }
