I am attempting to create a timesheet, where if a particular
cell is clicked
on, the current time/date stamp will generate via the Now()
function. I am
having trouble with how to indicate that the timestamp should
be entered if
the cell is clicked on. Also, can the timestamp be displayed
in the same
cell, take cell A1 for example. Any assistance is appreciated.
I have both
2000 and 2003 available.
