HELP... form lost all color and notes fields

Hello,
Just launched this to 100 of volunteers and the form lost all formatting with color and notes (headings) It is just a plain form with 80 fields now.  We need the form to be colored with heading in order for our volunteers to be able to use.  Can anyone tell me what I must have shut off or how to get around this?
If I edit the form, everything is there.  It is also there if I add a record.  Only when I click edit on a record from the data sheet do I not see anything but a plain form.  Anything you can do to offer help would be appreciated.
