When someone opens a workbook it records the day it was opened so I can use
it in a formula.
Example:
User opens on 5-1-05 at 12:00 p.m. = Now ( )
Closes on 5-1-05 at 5:00 pm.
Opens again on 5-2-05 at12:00 p.m.
Closes on 5-2-05 at 2:00 pm
Number of days or hours used = 2 days or 7 hours
Is there a formula that locks the 1st day 5-1-05, 12:00 p.m.
If it is a macro do I need a button to make it work or can I add the code to
an exisiting button or just when the workbook is opened for the first time.
