My game script is fine but I'm still getting unexpected class error

I am working on a game in Unity and I've asked someone who is quite experienced who fixed the script for me but I'm still getting these errors. We've done just about everyt$$anonymous$$ng and I've even updated and redownloaded Unity to try and fix t$$anonymous$$s but the script is still showing me errors.

Here's a screenshot of the errors: http://sta.sh/026p1e3f8i5n

I tried writing a new script, typing in exactly what was in the previous script but still received the same errors plus some new ones as well: http://sta.sh/01mxp83amcng

My friend who is helping me isn't experiencing t$$anonymous$$s problem and neither is their friend who tried it too so we're both pretty stuck on t$$anonymous$$s problem. My computer is an MSI all-in-one Gaming touchscreen: http://www.cnet.com/au/products/msi-ag270/ and the system it's using is windows 8.1 My friend is also using windows 8.1 so that can't be the issue.

We would both greatly appreciate any advice about t$$anonymous$$s as we can't figure out what the issue is. Here's a copy of the C# Script:

using UnityEngine; using System.Collections;

public class GamePlayer : MonoBehaviour {

 private Animator anim;
 using UnityEngine;
 using System.Collections;
 
 public class Player : MonoBehaviour {
     
     private Animator anim;
     
     // Use t$$anonymous$$s for initialization
     void Start () {
         anim = gameObject.GetComponentInC$$anonymous$$ldren<Animator> ();
     }
     
     // Update is called once per frame
     void Update () {
         
         if (Input.GetKey ("w")) {
             anim.SetInteger ("AnimPar", 1);
         } else {
             anim.SetInteger ("AnimPar", 0);
         }
         
         
         
         /*if (Input.GetKeyDown ("space")){
         anim.SetInteger ("Jump");
     } else {
         anim.SetInteger ("Jump");
     }*/
         
         /* SetInteger won't work because the function is expecting an integer as the second input value
     In the animator there are different params you can add:
         Integer (int)
         Float
         Boolean (bool)
         Trigger
     Each has their repective functions:
         SetInteger (paramName, int)
         SetFloat (paramName, float)
         SetBool (paramName, bool)
         SetTrigger (paramName) -- t$$anonymous$$s one has no second input
     More animator functions: https://docs.unity3d.com/ScriptReference/Animator.html
     
     You had it right, just you forgot to change the name of the function. But I t$$anonymous$$nk
     I told you to turn it into a bool, so use SetBool. You may also need to add extra
     code that handle your character touc$$anonymous$$ng the ground so that the jump can end.

         if (Input.GetKeyDown ("space")){
             anim.SetBool ("Jump", true);
         } // notice how i didn't add the second half of your original snippet
         // If i left it, then your character would have transistioned to standing w$$anonymous$$le in midair
         // when you let go of spacebar, and you probably don't want that
         // Goto OnCollisionEnter function to see the other half
     }
     
     //T$$anonymous$$s function reads collisions made in game, specificialy only the frame in w$$anonymous$$ch the object just
     //touched another object, hence on enter only.
     void OnCollisionEnter(Collision collisionInfo) {
         foreach (ContactPoint contact in collisionInfo.contacts) { //T$$anonymous$$s just seperates contacts
             if (Vector3.Angle(contact.normal, Vector3.up) < 45) { // T$$anonymous$$s if statement checks if the platform it collided with is flat enough to stand on
                 // platforms that are less than a 45 degree angle incline will not let t$$anonymous$$s part of the code run
                 anim.SetBool ("Jump", false); // If it is a "floor" then the jump animation will stop.
             }
         }
     }
     
     // make sure you have the transisions:
     // Idle => Jump (Condition: "Jump" == true)
     // Jump => Idle (Condition: "Jump" == false)
