Excel's Formula - sisman

Appendix D: What’s on the CD-ROM? 761
The files are Excel 2010 workbook files that have either of the following extensions:
XLSX: An Excel workbook file
XLSM: An Excel workbook file that contains VBA macros
When you open an XLSM file, Excel may display a Security Warning below the Formula bar. To
enable macros, click the Enable Content button in the Security Warning panel.
Because the files on this CD are from a trusted source, you may want to copy the files to your
hard drive, and then designate the folder as a trusted location. To do so, follow these steps:
1. Open an Explorer window, and select the CD-ROM drive that contains the companion
CD-ROM.
2. Right-click the folder that corresponds to the root folder for the example files, and select
Copy from the shortcut menu.
3. Activate the folder on your hard drive where you’d like to copy the files. Right-click the
directory, and then select Paste from the shortcut menu.
The CD-ROM files are then copied to a subfolder in the folder that you specified in Step 3. To
designate this new folder as a trusted location:
1. Start Excel and choose File➜Options to display the Excel Options dialog box.
2. In the Excel Options dialog box, click the Trust Center tab.
3. Click the Trust Center Settings button.
4. In the Trust Center dialog box, click the Trusted Locations tab.
5. Click the Add New Location button to display the Microsoft Office Trusted Location
dialog box.
6. In the Microsoft Office Trusted Location dialog box, click the Browse button, and locate
the folder that contains the files that you copied from the CD-ROM.
7. Make sure that you select the option labeled Subfolders of This Location Are Also Trusted.
After performing these steps, when you open XLSM files from this location, the macros are
enabled and you don’t see the security warning.
Following is a list of the chapter example files with a brief description of each. Note that not all
