Hi,

I have formatted the cells where I input the hours as hh:mm and
entered hours like start time of 8:15 and end time of 17:30. I then
take the 8:15 away from 17:30 and get 9:15 which is correct.
I have done this for several days, but when I try and calculate the
total hours worked to date I keep getting the wrong answer.
Any help will be greatly appreciated.

Thanks in advance.
All the Best
Paul
