• Include the $ symbol before both the column letter and the row
number to specify an absolute reference.
• Include a colon (:) between a two cell references to specify a range of
cells.
Absolute references include the $ symbol before the column letter and
before the row number (for example, $B$16). Absolute references always
refer to the cell in a specific position in the spreadsheet. The application
does not automatically adjust the cell reference when cell positions
change.
Typing a cell reference in a formula
1. Double-click the cell and type the formula. See the Calculator section
for details about inserting symbols and operators from the Catalog.
2. Move to the appropriate position in the formula and type the cell
reference. Use the format for a relative reference (B3), absolute
reference ($B$2), or range of cells (A1:A4).
