No one in my office can add.
I'm working on entering in timesheets, and while the rule is pretty much that they have to have 37.5 hours recorded (since that's our normal working hours) and therefore as long as they have 37.5 hours for the week it's good, it's amazing the totals that don't work.
First they record time by job. Horizontal line, total at the end. And most put the total at the bottom for how much they work each day. The problem is that the ones who total by day as well tend to then add up total hours worked by the day total. Somehow they manage to add wrong, and the total per job (which is what I enter for billing) comes out different from the total per day. Which probably just sounded like a bunch of random weirdness, but the result is their grand total not matching what I put in the system. Which doesn't matter to me, as long as it's more than 37.5 hours (and it usually is, except for the main boss who somehow does his timesheet and will record time for working 30 hours and think it's 37.5).
