I am Trying to find what position a Space is in my Array and get them to a array of floats

Well, based on our talk, here is what i can offer, i added the check solution. You are probably checking in another class, but this is an example of how to do the check when using my solution :

     using System.Linq;
     using System.Collections.Generic;
     using UnityEngine;
 
     public class WordDisplay : MonoBehaviour
     {
         public bool WordGuessed;
         private string currentWord;
         public string WordToGuess;
         private List<Transform> letters;
 
         public GameObject LetterPrefab;
         public GameObject SpacePrefab;
 
         void Start()
         {
             currentWord = null;
             WordToGuess = null;
             letters = new List<Transform>();
             WordGuessed = false;
         }
 
         private void ResetLetters()
         {
             WordGuessed = false;
             transform.DetachChildren();
             Transform l;
             while (letters.Count > 0)
             {
                 l = letters.First();
                 letters.RemoveAt(0);
                 Destroy(l);
             }
         }
 
         private void CreateWord()
         {
             char c;
             GameObject letter;
             for (int i = 0; i < WordToGuess.Length; i++)
             {
                 c = WordToGuess[i];
                 if (c == ' ')
                 {
                     letter = Instantiate(SpacePrefab);
                 }
                 else
                 {
                     letter = Instantiate(LetterPrefab);
                 }
 
                 letter.transform.parent = this.transform;
                 letters.Add(letter.transform);
             }
         }
 
         void Update()
         {
             if (currentWord != WordToGuess)
             {
                 ResetLetters();
                 CreateWord();
             }
             else
             {
                 //If a new word was not set
                 //Some other logic can be performed here
                 //For example checking if the entered letters are correct
                 WordGuessed = CheckLetters();
             }
         }
 
         private bool CheckLetters()
         {
             char userLetter;
             char wordLetter;
             for (int i = 0; i < letters.Count; i++)
             {
                 wordLetter = WordToGuess[i];
 
                 //Ignore space characters
                 if (wordLetter == ' ')
                 {
                     continue;
                 }
 
                 //Here you get the value of the letter in the box
                 //This example assumes there is a component containing the letter under the Value property
                 userLetter = letters[i].gameObject.GetComponent<SomeClass>().Value;
                 //Stop at first error, no need to go further
                 if (wordLetter != userLetter)
                 {
                     return false;
                 }
             }
             return true;
         }
 
         //A separate method that can be set on a button
         public void CheckWord()
         {
             WordGuessed = CheckLetters();
         }
     }

Hope this helps.
