I am rather new to Excel and I have a problem that I can not figure out how
to correct. I would appreciate any help you can give me.

All of a sudden one of my sheets is appearing double. It is hard to explain
so bear with me. When I open this one sheet, and scroll down there is a
divider and it appears in exact duplicate below the other. When I make
changes to one it also changes the other.
Please help.
