Changes column but doesn't change row to a new location. When you copy or fill a formula to other cells, the relative reference (column) adjusts to the new location but the absolute reference (row) stays the same. For example, if you copy the formula =A$1+3 from cell B2 to C2, the formula in C2 changes to =B$1+3.
