Question Saving from input field with TMPro

I am trying to update an project to saving the contents of an input field using TMPro instead of the legacy text. I am getting no errors but nothing is saving. Can anyone explain why the attached code doesn't work?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using TMPro;
6.  
7. public class SaveLoad : MonoBehaviour
8. {
9.     public string theText;
10.     public GameObject ourNote;
11.     public GameObject placeHolder;
12.    
13.     void start()
14.     {
15.             theText = PlayerPrefs.GetString("NoteContents");
16.             placeHolder.GetComponent<TMP_InputField>().text=theText;
17.      
18.     }
19.    
20.  
21.   public void SaveNote()
22.   {
23.         theText=ourNote.GetComponent<TMP_Text>().text;
24.         PlayerPrefs.SetString("NoteContents", theText);
25.  
26.   }
27.   }
