Double-click the first form field (while the document is unprotected).

Press Ctrl+F9 to insert field braces { } (do not type { } yourself, that won't work!)

Press F9 to hide the field code.
When you protect the document for forms, enter something in the form field and press Tab, the reference(s) elsewhere in the document will be updated.
