Unexpected symbol '{ ,= ,; in, ), !=, && ,== ,< , etc. etc.' in class, struct, or interface member declaration.

So, I've been following this tutorial (https://www.youtube.com/watch?v=EyRPmhyrVUs) on Raycast shooting in Unity, and I can't figure out why this is happening. Here's my code:

using UnityEngine; using System.Collections;

public class NewBehaviourScript : MonoBehaviour {

 // Use this for initialization
 void Start () {
     if (Input.GetButton ("Fire1")) {
     }
 }
 
 // Update is called once per frame
 void Update () {
 
 }

 void Fire () {
     Ray ray = new Ray(Camera.main.transform.position, Camera.main.transform.forward);
     Transform hitTransform;
     Vector3 hitPoint;

     FindClosestTransform(ray, hitPoint);
 }

 Transform FindClosestTransform(Ray ray, out Vector3 hitPoint); {
     RaycastHit[] hits = Physics.RaycastAll (ray);

     Transform closestHit = null;
     float distance = 0;
     hitPoint = Vector3.zero;

     foreach (RaycastHit hit in hits) {
         if(hit.transform != this.transform && (closestHit == null || hit.distance < distance)) {
             closestHit = hit.transform;
             distance = hit.distance;
             hitPoint = hit.Point;
         }
     }
     Debug.Log("We just hit: " + closestHit.name + " with a BLANK");

     return closestHit;
 }

}

Where ever it says "= hit", whether that be 'closestHit = hit.transform;' or 'distance = hit.distance;' or 'hitPoint = hit.Point;', there's a red line. It says it's an unexpected symbol. There's also one where it says "= Vector3.zero" between the '=' and 'Vector3'. So, that led me to believe it was just those that were 'unexpected'. But, when I had looked at my Console, I got tons and tons of Compiler Error that all said the same unexpected symbol thing. This time though, it was with lots of operators. Ex: '{ ,= ,; in, ), !=, && ,== ,< , etc. etc.' Can anyone help? I am a super noob with Unity and C#, as you may have been able to tell.
