I tried to make a ragdoll game and had the idea of making it a fun draggable ragdoll as my first game,tried making the drag script but i get this error: error CS0030: Cannot convert type ‘method’ to ‘Vector2’

Here is the script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class StickManDragger : MonoBehaviour
{
    Vector2 difference = Vector2.zero;

    private void OnMouseDown()
    {
        difference = (Vector2)Camera.main.ScreenToWorldPoint - (Vector2)transform.position;
    }

    private void OnMouseDrag()
    {
        transform.position = (Vector2) Camera.main.ScreenToWorldPoint(Input.mousePosition) - difference;
    }


}

difference = (Vector2)Camera.main.ScreenToWorldPoint - (Vector2)transform.position;
this should be:
difference = (Vector2)Camera.main.ScreenToWorldPoint(Input.mousePosition) - (Vector2)transform.position;
