I accidentally turned off the tool where it shows the sum at the bottom right
of the screen when you highlight cells. I was told that righ-clicking the
bottom right hand side of the scrren would display some options, with "sum"
being one of them. However, the box that the sum is usually displayed in
isn't on the screen anymore either, and there is no Sum option that displays
when I right click. Did I perhaps turn of something else, or delete the box
somehow? I'm not sure. Thanks for your help.
