All the comments fields are no plain text fields.
The JS checks the comments fields (in Red ellipses) and if there is some text in one then the text is added to the Comments history field at the bottom along with a timestamp and the approver (Blue elipses), each comments field is checked independantly.
The attached images show the form layout and the results in the console log window after typing in some text.
If I query another field that already has text in it it returns the text (second screenshot)
