I followed some Indonesian guy in YouTube on how to make a Word Scrabble. However, what really bugs me the most is the GetComponent Error and that error is shown above, highlighted. I already followed what he type (not says because I can’t understand bahasa and this is the only game that has close resemblance to PopCap’s Text Twist). Please help. 
Here’s the code for each CS:
WordScramble.CS
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
[System.Serializable]
public class Word
{
public string word;
[Header("leave empty if you want randomized")]
public string desiredRandom;
public string GetString()
{
if (!string.IsNullOrEmpty (desiredRandom))
{
return desiredRandom;
}
string result = word;
while (result == word)
{
result = "";
List<char> characters = new List<char> (word.ToCharArray ());
while (characters.Count>0)
{
int indexChar = Random.Range(0, characters.Count - 1);
result += characters[indexChar];
characters.RemoveAt (indexChar);
}
}
return result;
}
}
public class WordScramble : MonoBehaviour {
public Word[] words;
[Header("UI REFERENCE")]
public CharObject prefab;
public Transform container;
public float space;
List<CharObject> charObjects = new List<CharObject>();
CharObject firstSelected;

}
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
void RepositionObject()
{
if (charObjects.Count == 0)
{
return;
}
float center = (charObjects.Count - 1) / 2;
for (int i = 0; i < charObjects.Count;i++)
{
charObjects[i].rectTransform.anchoredPosition
= new Vector2((i - center) * space, 0);
charObjects[i].index=1;
}
}

public void ShowScramble(int index)
{
charObjects.Clear ();
foreach(Transform child in container)
{
Destroy(child.gameObject);
}
if (index > words.Length - 1)
{
Debug.LogError ("index out of range, please enter range betweeen 0-" + (words.Length - 1).ToString());
return;
}
char[] chars = words[index].GetString().ToCharArray();
foreach (char c in chars)
{
CharObject clone = Instantiate(prefab.gameObject).GetComponent<CharObject>();
clone.transform.SetParent(container);
charObjects.Add(clone.Init(c));

public void Select(CharObject charObject)
{

//unselect

firstSelected.Select();
charObject.Select ();
} else

}
public void Unselect()
{

}
public bool Checkword()

}
if (word == words [currentWord].word)

return true;

}
and CharObject.CS
