I've got an excel spreadsheet that tracks attendance (time in/out). We
work 8 or 10 hour days depending on the shift. We are required to be
as close to 0 hrs over/under at the end of each month however we
sometimes carry a balance of x amount of minutes.

My goal is to create a cell that you can input your time over/under
into which represents any overage/underage from the previous month.
This cell will then add into the cumulative +/- total for the current
month so that you know when to clock out for the day.

My Cumulative +/- cell has this formula

=SUM($F$16:F$46+D8)

Where column F represents a time value of Time Out - Time In and D8
represents the previous months' time +/- in h:mm format

The formula isn't working and I don't know why......
