Here is the code I used. I created a command button and used the code you recommended and it works beautifully. Thank you so much

Private Sub CommandButton1_Click()
With ActiveDocument.FormFields("Text124")
.Result = "Entered by " & Environ("Username") & " on " & Format(Now(), "DDDD, D MMMM YYYY @ hh:mm")
.Enabled = False
End With

End Sub
