Spreadsheet 7-23 Circular reference Circular references Avoid circular references in a spreadsheet. A circular reference occurs when two or more cells refer to each other-for example when cell A1 contains =B2*3 and cell B2 contains =A1+4. A circular reference also occurs when a cell refers to itself, for example, in the formula A10=SUM(A1..A10). AppleWorks marks cells that contain circular references with bullets. To turn off the markings, choose Display from the Options menu, and then deselect Mark circular refs. Entering formulas In the Help index,* see: E arithmetic operators E spreadsheets, calculations You can type each of the formula elements or have AppleWorks enter cell references and functions for you. To enter a formula, select the cell where you want the formula's result to go and type an equal sign (=) in the entry bar. Type the formula after the equal sign (you can put a space before or after any operators), and then click to confirm your entry. Tip You can quickly total the values in selected cells and display the result in the row or column cell adjacent to the selected cells. Select the cells (including a blank cell to display the total) and click on the Default button bar. Before Select the cells to be totaled After and the cell for the result To Do this Example Enter a reference to a single cell Click to select the cell that you want to =B1+C1 refer to. AppleWorks enters a plus sign (+) when you click the next cell. (To use a different operator-such as * to multiply- =B1*C1 type the operator before you click the next cell.) AppleWorks inserts the cell reference at the insertion point in the formula. * Choose Index from the or Help menu and scroll to the entry. Then choose a topic from the list and click Go To Topic.

Circular references
Avoid
circular references
in a spreadsheet. A circular
reference occurs when two or more cells refer to each other—for example
when cell A1 contains =B2*3 and cell B2 contains =A1+4. A circular
reference also occurs when a cell refers to itself, for example, in the formula
A10=SUM(A1..A10).
AppleWorks marks cells that contain circular references with bullets. To
turn off the markings, choose
Display
from the Options menu, and then
deselect
Mark circular refs
.
Entering formulas
You can type each of the formula elements or have AppleWorks enter cell
references and functions for you. To enter a formula, select the cell where
you want the formula’s result to go and type an equal sign (=) in the entry
bar. Type the formula after the equal sign (you can put a space before or after
any operators), and then click
to confirm your entry.
Tip
You can quickly total the values in selected cells and display the result
in the row or column cell adjacent to the selected cells. Select the cells
(including a blank cell to display the total) and click
on the Default button
bar.

Example
Enter a reference to

Click to select the cell that you want to
refer to. AppleWorks enters a plus sign (+)
when you click the next cell. (To use a
different operator—such as * to multiply—
type the operator before you click the next
cell.) AppleWorks inserts the cell reference
at the insertion point in the formula.
