i created a spreadsheet where i will be tracking hours for our sales people.
i want to automatically track what hours they work. they usually send me the
time as (ex. 10 - 7,). I would like to get a formula that would automatically
add the time up as hours worked and automatically deduct an hour off for
lunch. can someone help me with this?
