  The text that is submitted using your `<input>` field will display as expected with `Your Reference: {{ cart.customerReference }}`.
  
  However, I have a feeling that because the page is re-rendered with the inputs `value` as empty, when the `/updateCart` action is submitted again the blank value will override and erase the old value.
  
  To solve this use the `customerReference` stored on the cart in the `value` attribute of your text `<input>`.
  
  ```
  <input ... value="{{ cart.customerReference|length ?? cart.customerReference }}">
  
  ```
