Hi, I'm simply trying to subtract hours in one field from hours in another. I have a column with 'hours recorded' and one with 'hours billed'. They are both formatted as time units (hours). I just want to subtract one from the other in a new field. As an additional question is there a way to set the hour units to just hours, with no minutes, at the moment it's h:mm and I need to enter a 0 for minutes each time Thanks
