Instantiate a partical system

so im trying to Instantiate a particle system that i have made into a prefab, so when i pick a object up it destroys it and creates Instantiates the particle system where it was. the problem is its saying a cant use the object's(the one i need to pick up, which is "HitObject") position as the second thing in the Instantiate command.

 public Transform ParticalSystem;
 public float Timeout = 3;     
 private Transform HitObject;
 private RaycastHit hit;
 public int GrabDis = 6;         
 private bool ChangeIcon = false;
 
 void Update ()
 {    
 if (Physics.Raycast(ray, out hit, GrabDis))
         {
             if (hit.collider.gameObject && hit.collider.gameObject.tag == "Bear")
             {
                 Transform HitObject = hit.collider.gameObject.transform;
                 ChangeIcon = true;
                 Debug.Log("hit bear");
                 if (Input.GetKeyDown(KeyCode.E))
                 {
                     Transform partical;
                     partical = Instantiate(ParticalSystem, HitObject.transform, transform.rotation) as Transform;
                     Destroy(hit.transform.gameObject);
                     Destroy(ParticalSystem, Timeout);
                 }
             }
             if (hit.collider.gameObject.tag != "Bear")
             {
                 ChangeIcon = false;
                 Debug.Log("Not hiting bear");
             }
         }
     }
