Relative address is relative to the active cell. If in cell A1 you have =B2,
you REALLY have a reference to one cell down and one to the right. So if you
were to copy cell A1 with that formula and paste it to cell H77, you'd see
=I78 which is still one cell down & one to the right. However, if cell A1
contained an absolute address like =$B$2, this refers to cell B2. If you
copy cell A1 to H77, you'd see =$B$2.
