The name `gameObject' does not exist...? Yes i did my research.

TTA_Coord.cs(12,15): error CS0103: The name `gameObject' does not exist in the current context

Please help me make this disappear. I have looked this up and have not been able to apply the solutions to my code sucessfully. I am working on a unique project and I need a script attached to a sprite that references a non Mono behaviour scripts "X Y and Z" integers. Here is the script (walker) thats supposed to do the referencing.

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class Walker : MonoBehaviour {
 
     //Storing the reference to RagePixelSprite -component
     private IRagePixel ragePixel;
      
     //enum for character state
     public enum WalkingState {Standing=0, WalkRight, WalkLeft};
     public WalkingState state = WalkingState.Standing;
 
         
     //walking speed (pixels per second)
 
     
      GameObject coordPosit;
 
     
 
     void Start () {
         ragePixel = GetComponent<RagePixelSprite>();
      coordPosit= GameObject.Find("TTA_Coord").GetComponent<TTA_Coord> ();
 
     }
 
     
 
 
     
     
     
     
     void Update () {
 TTA_Coord coordPos = coordPosit.GetComponent<TTA_Coord>();
         //Check the keyboard state and set the character state accordingly
         if (coordPos.x == 5 && coordPos.y == 5 && coordPos.z == 0)
         {
             state = WalkingState.WalkLeft;
         }
         else if (coordPos.x == 5 && coordPos.y == 6 && coordPos.z == 0)
         {
             state = WalkingState.WalkRight;
         }
         else
         {
             state = WalkingState.Standing;
         }
 
         
         switch (state)
         {
             case(WalkingState.Standing):
                 ragePixel.SetSprite("Dripper", 0);
                 //Reset the horizontal flip for clarity
                 ragePixel.SetHorizontalFlip(false);
                 ragePixel.PlayNamedAnimation("drip", false);
                 break;
             
             case (WalkingState.WalkLeft):
                 ragePixel.SetSprite("Dripper", 0);
                 //Flip horizontally. Our animation is drawn to walk right.
                 ragePixel.SetHorizontalFlip(true);
                 //PlayAnimation with forceRestart=false. If the WALK animation is already running, doesn't do anything. Otherwise restarts.
                 ragePixel.PlayNamedAnimation("drip", false);
                 //Move direction. X grows right so left is -1.
                 
                 break;
 
             case (WalkingState.WalkRight):
                 ragePixel.SetSprite("Barred", 0);
                 //Not flipping horizontally. Our animation is drawn to walk right.
                 ragePixel.SetHorizontalFlip(false);
                 //PlayAnimation with forceRestart=false. If the WALK animation is already running, doesn't do anything. Otherwise restarts.
                 ragePixel.PlayNamedAnimation("there", false);
                 //Move direction. X grows right so left is +1.
                 
                 break;
         }
 
         //Move the sprite into moveDirection at walkingSpeed pixels/sec
         
     }
 }

And here's the script (TTA_Coord) thats supposed to be referenced...

 using System;
 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 
 public class TTA_Coord 
 {
     
         void Start () {
 
     fbs = gameObject.AddComponent<Walker>();
 
 
     }
 
     
 
  public Walker fbs;
     
     
     
     public int x = 0;
     public int y = 0;
     public int z = 0;
     
     public override string ToString ()
     {
         return x + "," + y + "," + z;
     }
     
     public TTA_Coord(){}
     
     public TTA_Coord(int x, int y, int z){
         this.x = x;
         this.y = y;
         this.z = z;
     }
     
     public bool IsValid(){
         return (this.x >= 0 && this.y >= 0 && this.z >= 0);
     }
     
     public TTA_Coord(TTA_Coord source, TTA_CommandType command){
         
         if(source == null){
             return;
         }
         
         this.x = source.x;
         this.y = source.y;
         this.z = source.z;
         
         switch(command){
             
             case TTA_CommandType.North:{
                 this.y -= 1;
                 break;
             }
             case TTA_CommandType.South:{
                 this.y += 1;
                 break;
             }
             case TTA_CommandType.East:{
                 this.x +=1;
                 break;
             }
             case TTA_CommandType.West:{
                 this.x -=1;
                 break;
             }
             case TTA_CommandType.Up:{
                 this.z += 1;
                 break;
             }
             case TTA_CommandType.Down:{
                 this.z -=1;
                 break;
             }
             
         }
     }
     
     public TTA_Coord(TTA_Coord source){
         
         if(source == null){
             return;
         }
         
         this.x = source.x;
         this.y = source.y;
         this.z = source.z;
     }
     
     public override bool Equals (object obj)
     {        
         if(!(obj is TTA_Coord)){
             
             return false;
         }
                 
         TTA_Coord comp = (TTA_Coord)obj;
         
         if(comp.x == x &&
             comp.y == y &&
             comp.z == z){
             
             return true;
             
         }
         
         return false;
     }
     
     public override int GetHashCode ()
     {
         return x + (10*y) + (100*z);
         
     }
     
 }

Any help would be gladly appreciated. Thanks bunches. --TheIronHobo
