Chapter 9 Formula Editor 295
Using Functions
To create a formula that contains a function
1 Open the formula editor by right-clicking a column name in the data grid and selecting Formula.
2 Select an expression in the formula editing area by clicking it. (It is selected when there is a red
outline around it.) The function performs its action on the area that is highlighted.
3 Click the menu in the function browser to view the groups of functions.
4 Select a group of functions to view. (See Table 9.3 for details.) The functions that belong to that
group are then displayed in the list below the menu. The function groups are briefly described in the
following list. For a full description, see the following sections, starting with “Referencing Rows,”
p. 297.
5 Click any function in the Functions list to apply it to the selected item. When you click some items,
you reveal a submenu from which you should make a selection.

Note: Most formulas give hints about appropriate arguments through gray words inserted in the boxes
in the formula editing area. Formulas also show a small caret in the argument area if additional
arguments can be added.
6 Continue to build the formula by highlighting terms and clicking items in the formula element
browser, keypad, or function browser.
