Problem with raycast detection?

Ok, so I made a script for grid like movement, and it worked before I started working on adding the obstruction via raycasting. As soon as I added raycasting for obstruction detection, I wasn't getting any errors, but my player is not able to move anymore. I have tried to fix it based on examples, and I have tried this for about a few hours with no luck. Anyone proficient enough in C# to help a new coder like me find the problem? (My code might be a bit of a mess, i just started coding about 2 weeks ago.)

 using UnityEngine;
 using System.Collections;
 
 public class MoveScript : MonoBehaviour {
 
     public bool forwardObstruction = false; // Next few bools are to register if there is an obstruction-
     public bool backwardObstruction = false; // -in the given direction.
     public bool leftObstruction = true;
     public bool rightObstruction = true;
     public float inputDelay = 0.05f; //Stating how many seconds before we can move again.
     public Vector3 forwardDirection; //These next few vectors are direction values.
     public Vector3 backwardDirection;
     public Vector3 leftDirection;
     public Vector3 rightDirection;
     public int smoothFactor = 2; // Not used yet
     public int lineLength = 2; // Not used yet
 
 
     private float timestamp;    
 
         // Update is called once per frame
         void Update () {
 
         // Creates a raycast line forward based on lineLength, checks to see if path is obstructed.
         Vector3 fwd = transform.TransformDirection(Vector3.forward);
         if (Physics.Raycast(transform.position, fwd, lineLength)){
             forwardObstruction = true;
         }
             else
             forwardObstruction = false;
     
         
         Vector3 bwd = transform.TransformDirection(Vector3.back);
         if (Physics.Raycast (transform.position, bwd, lineLength)) {
             backwardObstruction = true;
         }
             else
             backwardObstruction = false;
 
         Vector3 left = transform.TransformDirection(Vector3.left);
         if (Physics.Raycast (transform.position, left, lineLength)) {
             leftObstruction = true;
         }
         else
             leftObstruction = false;
 
         Vector3 right = transform.TransformDirection(Vector3.right);
         if (Physics.Raycast (transform.position, right, lineLength)) {
             rightObstruction = true;
         }
         else
             rightObstruction = false;
 
 
             //See if the "Forward" key is pressed
         if (forwardObstruction == true && Time.time >= timestamp && Input.GetButton ("Forward")) {
                         transform.Translate (forwardDirection);
                         timestamp = Time.time + inputDelay;
                         forwardObstruction = forwardObstruction;
                 }
             //See if the "Backward" key is pressed
         if (backwardObstruction == true && Time.time >= timestamp && Input.GetButton("Backward"))  {
                         transform.Translate (backwardDirection);
                         timestamp = Time.time + inputDelay;
                 }
             //See if the "Left" key is pressed
         if (Time.time >= timestamp && Input.GetButton ("Left")) {
                         transform.Translate (leftDirection);
                         timestamp = Time.time + inputDelay;
                 }
             //See if the "Right" key is pressed
         if (Time.time >= timestamp && Input.GetButton ("Right")) {
                         transform.Translate (rightDirection);
                         timestamp = Time.time + inputDelay;
                 }
         }
 }

Any help is appreciated, thank you for at least looking!
