Assets\InputHandler.cs(17,20): error CS1519: Invalid token ';' in class, record, struct, or interface member declaration

It says that there shouldn't be a ';' after 'Camera.main' but when I remove it, another error appears saying that it should be there. Can someone help me?

Here is my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 namespace JG
 {
     public class InputHandler : MonoBehaviour
     {
         public float horizontal;
         public float vertical;
         public float moveAmount;
         public float mouseX;
         public float mouseY;
 
         PlayerControls inputActions;
 
         Camera.main;
 
         Vector2 movementInput;
         Vector2 cameraInput;
 
         public void OnEnable()
         {
             if (inputActions == null)
             {
                 inputActions = new PlayerControls();
                 inputActions.PlayerMovement.Movement.performed += inputActions => movementInput = inputActions.ReadValue<Vector2>();
                 inputAction.Camera.performed += i => cameraInput = i.ReadValue<Vector2>();
             }
             inputActions.Enable();
         }
 
         private void OnDisable()
         {
             inputActions.Disable();
         }
 
         public void TickInput(float delta)
         {
             MoveInput(delta);
         }
 
         private void MoveInput(float delta)
         {
             horizontal = movementInput.x;
             vertical = movementInput.y;
             moveAmount = Mathf.Clamp01(Mathf.Abs(horizontal) + Mathf.Abs(vertical));
             mouseX = cameraInput.x;
             mouseY = cameraInput.y;
         }
     }
 }
