Hi! I'm a VF novice and I'm trying to add a new Section header and field to an existing VF Quote page, however neither are showing up on the Quote page. The existing code is pasted below with the section/field  I'm trying to add that is not showing up highlighted in yellow. Not sure what I'm doing wrong.

Any help or advise on this will be very much appreciated!

Thanks!
