Trying to make pointer, but ScreenToWorldPoint wont work

Heres my code void FixedUpdate() { Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition); transform.position = mousePosition; Debug.Log(Camera.main.ScreenToWorldPoint(Input.mousePosition)); }

But no matter how much i move the mouse, the debug log says it isnt working. Id love some help.
