38 Part I: Basic Information Protecting a workbook’s structure When you protect a workbook’s structure, you can’t add or delete sheets. Use the Review➜ Changes➜Protect Workbook command to display the Protect Structure and Windows dialog box, as shown in Figure 1-15. Make sure that you enable the Structure check box. If you also mark the Windows check box, the window can’t be moved or resized. Figure 1-15: To protect your workbook’s structure, select the Structure check box. Keep in mind that Excel is not really a secure application. The protection features, even when used with a password, are intended to prevent casual users from accessing various components of your workbook. Anyone who really wants to defeat your protection can probably do so by using readily available password-cracking utilities. Password-protecting a workbook In addition to protecting individual sheets and the structure of the workbook, you can require a password to open the workbook. To set a password, choose File➜Info➜Protect Workbook➜ Encrypt With Password to display the Encrypt Document dialog box (see Figure 1-16). In this dialog box, you can specify a password to open the workbook. Figure 1-16: Use the Encrypt Document dialog box to specify a password for a workbook.
2 Basic Facts about Formulas In This Chapter ● How to enter, edit, and paste names into formulas ● The various operators used in formulas ● How Excel calculates formulas ● Cell and range references used in formulas ● How to make an exact copy of a formula ● How to convert formulas to values ● How to prevent formulas from being viewed ● The types of formula errors ● Circular reference messages and correction techniques ● Excel’s goal seeking feature This chapter serves as a basic introduction to using formulas in Excel. Although I direct its focus on newcomers to Excel, even veteran Excel users may find some new information here. Entering and Editing Formulas This section describes the basic elements of a formula. It also explains various ways of entering and editing your formulas. Formula elements A formula entered into a cell can consist of five elements: Operators: These include symbols such as + (for addition) and * (for multiplication). Cell references: These include named cells and ranges that can refer to cells in the current worksheet, cells in another worksheet in the same workbook, or even cells in a worksheet in another workbook. 39
