Hi,

I have an excel sheet in that there are 4 columns,

1.Current Date
2.Start Time
3.End Time
4.User Name

Now what i want to do is i need 2 button for Start time & end time cells, when i clicked on start button the time should start and user name and current date should come automatically and once i clicked on start again it should not work unless i click on end button and the i should not be able to edit the sysem generated start time and end time. Please help.
