[GUI] Conditional Trigger for Button is flawed

Problem: My finish button in the first code of text wont appear when the conditions are met. What is the flaw in my code? Someone please help.

I have a script in my DisplayCreatePlayerFunctions file:

 using UnityEngine;
 using System.Collections;
 
 public class DisplayCreatePlayerFuntions
 {
     private StatAllocationModule statAllocationModule = new StatAllocationModule();
 
     private int classSelection;
     private string[] classSelectionNames = new string[] { "Human", "Kiriko" };
 
 
     public void DisplayClassSelections()
     {
         //List of toggle buttons and each button will be a different class via selection grid
 
         classSelection = GUI.SelectionGrid(new Rect(50,50,250,300), classSelection, classSelectionNames, 2);
         GUI.Label(new Rect(320, 50, 300, 300), FindClassDescription(classSelection));
         GUI.Label(new Rect(320, 100, 300, 300), FindClassStatValues(classSelection));
         
 
     }
 
     private string FindClassDescription(int classSelection)
     {
         if (classSelection == 0)
         {
             BaseCharacterClass tempClass = new BaseHumanClass();
             return tempClass.CharacterClassDescription;
         }
         else if (classSelection == 1)
         {
             BaseCharacterClass tempClass = new BaseKirikoClass();
             return tempClass.CharacterClassDescription;
         }
         return "WIP";
     }
 
     private string FindClassStatValues(int classSelection)
     {
         if (classSelection == 0)
         {
             BaseCharacterClass tempClass = new BaseHumanClass();
             string tempStats = "Stamina " + tempClass.Stamina + "\n" + "Endurance" + tempClass.Endurance + "\n" + "Agility " + tempClass.Agility + "\n" + "Speed " + tempClass.Speed + "\n" + "Control " + tempClass.Control + "\n" + "Strength " + tempClass.Strength;
             return tempStats;
         }
         else if (classSelection == 1)
         {
             BaseCharacterClass tempClass = new BaseKirikoClass();
             string tempStats = "Stamina " + tempClass.Stamina + "\n" + "Endurance" + tempClass.Endurance + "\n" + "Agility " + tempClass.Agility + "\n" + "Speed " + tempClass.Speed + "\n" + "Control " + tempClass.Control + "\n" + "Strength " + tempClass.Strength;
             return tempStats;
         }
         return "WIP";
     }
 
 
     public void DisplayStatAllocation()
     {
         //A list of stats with a plus to add stats
         statAllocationModule.DisplayStatAllocationModule();
         
     }
 
     public void DisplayFinalSetup()
     {
         //name/gender/add a player desc.
 
     }
 
     private void ChooseClass(int classSelection)
     {
         if (classSelection == 0)
         {
             GameInformation.PlayerClass = new BaseHumanClass();
         }
         else if (classSelection == 1)
         {
             GameInformation.PlayerClass = new BaseKirikoClass();
         }
     }
 
     public void DisplayMainItems()
     {
         GUI.Label(new Rect(Screen.width / 2, 20, 250, 100), "Create New Player");
 
         if (CreateAPlayerGUI.currentState != CreateAPlayerGUI.CreateAPLayerStates.FINALSETUP)
         {
             if (GUI.Button(new Rect(470, 370, 50, 50), "Next"))
             {
                 if (CreateAPlayerGUI.currentState == CreateAPlayerGUI.CreateAPLayerStates.CLASSSELECTION)
                 {
                     ChooseClass(classSelection);
                     CreateAPlayerGUI.currentState = CreateAPlayerGUI.CreateAPLayerStates.STATALLOCATION;
                 }
                 else if (CreateAPlayerGUI.currentState == CreateAPlayerGUI.CreateAPLayerStates.STATALLOCATION)
                 {

                     if (GUI.Button(new Rect(470, 370, 50, 50), "Finish"))
                     {
                         Debug.Log("MAKE FINAL SAVE");
                     }
                 }
             }
         }
 
         if (GUI.Button(new Rect(295, 370, 50, 50), "Back"))
         {
             if (CreateAPlayerGUI.currentState == CreateAPlayerGUI.CreateAPLayerStates.STATALLOCATION)
             {
                 CreateAPlayerGUI.currentState = CreateAPlayerGUI.CreateAPLayerStates.CLASSSELECTION;
             }
             else if (CreateAPlayerGUI.currentState == CreateAPlayerGUI.CreateAPLayerStates.FINALSETUP)
             {
                 CreateAPlayerGUI.currentState = CreateAPlayerGUI.CreateAPLayerStates.STATALLOCATION;
             }
 
         }
     }
 
 }
 

Here is the CreateAPlayerGUI File:

 using UnityEngine;
 using System.Collections;
 
 public class CreateAPlayerGUI : MonoBehaviour {
 
     public enum CreateAPLayerStates
     {
         CLASSSELECTION, //display stat types
         STATALLOCATION, //allocate stats
         FINALSETUP // add name, and gender
 
     }
 
     private DisplayCreatePlayerFuntions displayFunctions = new DisplayCreatePlayerFuntions();
     public static CreateAPLayerStates currentState;
 
     // Use this for initialization
     void Start () {
         currentState = CreateAPLayerStates.CLASSSELECTION;
     
     }
     
     // Update is called once per frame
     void Update ()
     {
         switch(currentState)
         {
             case (CreateAPLayerStates.CLASSSELECTION):
                 break;
             case (CreateAPLayerStates.STATALLOCATION):
                 break;
             case (CreateAPLayerStates.FINALSETUP):
                 break;
         }
     
     }
     void OnGUI()
     {
         displayFunctions.DisplayMainItems();
 
         if (currentState == CreateAPLayerStates.CLASSSELECTION) //
         {
             displayFunctions.DisplayClassSelections();
         }
         if (currentState == CreateAPLayerStates.STATALLOCATION) //
         {
             displayFunctions.DisplayStatAllocation();
         }
         if (currentState == CreateAPLayerStates.FINALSETUP) //
         {
             displayFunctions.DisplayFinalSetup();
         }
     }
