Hi Lois
First, try the simplest method. Do View > Header and Footer. Now, Tools >
Customize and click the Toolbars tab. If the Header and Footer toolbar is
ticked, then the toolbar may be displayed, but for some reason you can't see
it. Have a good look around in your toolbars, moving them around if
necessary, to see if th H&F toolbar might be displayed off screen or amongst
other toolbars.
If that doesn't work, see
My menus and toolbars are missing and won't come back
