Hi
Sorry, but I doubt anyone is going to reply to this. Take your time and
rewrite the question. What does the table of data you are working with
look like, what is this function supposed to do with it exactly? When
is 1 hour deducted and when is a half hour deducted and from what? A
total hours column is a total of what things exactly ( Time off, Time
at work, Time worked so far, total hours of all staff, total hours by
one staff member this week, this month???)?

regards
Paul
