Absence Tracker will not calculate

I thought my problem was solved ... but now I have another dilemma. I have added the names to the total column and the subsequent tabs don't change. I started doing it manually and thought there has got to be a better way. That is one issue.

The second issue is I can't seem to get the numbers to subtract from the total (See Diane Cantey for example). I place the time in and it does not show up in the total tab.

Please help again! Document attached.
