Can anyone help me find the problems in this code?

I was following a simple game tutorial and struck quite alot of problems. I was hoping someone would help. I put comments where it says the problem is but idk what to even do there. I got an error cs1547 (41,27) cs 1525(41,28) cs0116(41,28) and last a error cs8025 (56,1)

public class playerMovement : MonoBehaviour { public float moveSpeed; private float maxSpeed = 5f; private Vector3 input; private Vector3 spawn; public GameObject PlayerDeathParticles;

 // Use this for initialization
 void Start () {
     spawn = transform.position;
 
 }
 
 // Update is called once per frame
 void Update () {
     input = new Vector3 (Input.GetAxisRaw ("Horizontal"), 0, Input.GetAxis ("Vertical"));//movement controls
     if (GetComponent<Rigidbody> ().velocity.magnitude < maxSpeed) {
         GetComponent<Rigidbody> ().AddForce (input * moveSpeed);

     }
     if (transform.position.y < -2 )
     {
         Die ();
     }

 }


 void OnCollisionEnter (Collision other)
 {
     if (other.transform.tag == "Enemy") {
     {
         Die ();
     }                

 }

     void OnTriggerEnter(Collision other)//this has a red line under it
 {
         if (other.transform.tag == "Goal")
         {
             GameManager.CompleteLevel ();
         }
     
 }

 void Die ()// this has a red line under it
 {
     Instantiate (PlayerDeathParticles, transform.position, Quaternion.Euler(270.0.0));
     transform.position = spawn;
 

}
