Excel 2003 Macros Won't Run

1. Click on 'Tools,' then click on 'Macros,' then click on 'Security.' Check to see if the 'High' radio button is selected. If it is, this is likely preventing your macros from running. Click on the 'Medium' button for the security level and then click on 'OK.'
2. Save your worksheet if Step 1 didn't work, then close Excel completely. Restart Excel and reopen the worksheet.
3. Repeat Step 1 and Step 2. This should resolve the quirk preventing the macros from running.
