To reset the security level for Excel 2003 and earlier versions,

1. If the program containing the macros is open, close it and exit Excel.2. Re-open Excel, click on "Tools" on the main tool bar, select "Macro", select "Security."

3. Reset security level to Medium (recommended) or Low

4. Exit Excel

5. Re-open Excel
