You could put it in the ThisWorkBook module, and declare it as an event
handler, such as:

Private Sub Workbook_Open()
'your code here
End Sub

This example would run whenever the workbook is opened. If you click on the
drop down boxes in the ThisWorkBook module you'll see there are a variety of
events to which you could attach your code.

The code works fine, but how and where do you put it for it to start
automatically. I have it in a Module but I have to manually go in and run it
from there.
Sub clock()
If ThisWorkbook.Worksheets(1).Range("C2").Value = "X" Then Exit Sub
ThisWorkbook.Worksheets(1).Range("G2").Value = Format(Now, "hh:mm:ss AM/PM")
Application.OnTime Now + TimeSerial(0, 0, 60), "clock"
End Sub
Thanks in Advance!
