Here are my Excel files.
If you like you can look at the notes and ScreenShot pictures first to get an idea of what they do.
It is best to download the files first and then open them in Excel rather than open them in a browser window.
To download right click on the link and choose "Save Target As" or "Save Link as".
Setting up Excel
Nearly all the workbooks use macros. In order to enable the macros you will need to set the security level to medium or zero in Excel (for Excel 2003 go to Tools/Macros /Security).
In Excel 2003 some files need the Excel optional add-ins Analysis ToolPak and Analysis ToolPak VBA; follow these instructions to make sure you have them installed and enabled:
On the Tools menu, click Add-Ins.
If the add-in you want to use is not listed in the Add-Ins available box, click Browse, and then locate the add-in. If the add-in is not installed on your computer, you can install it (you may need your Office installation disk).
In the Add-Ins available box, select the check box next to the add-in you want to load.
For more detail type "Install add-in" into the Excel help Answer Wizard.
