I think this is simple, but I cannot figure this out!

Maybe it is the layout but I was trying to keep it simple and just put hours into a cell for each employee.
I have 2 employees per day, one in the morning and one in the evening. I need advice on how to get excel to add the hours for each employee at the bottom per month. Simple right?

Here is an example of what I thought would be so easy (first week in excel spreadsheet format)

sun mon tue wed thu fri sat
emp1 5 emp3 6 emp5 5 emp1 4 emp3 5 emp5 5 emp1 6
emp2 5 emp4 5 emp6 5 emp2 5 emp4 5 emp6 6 emp2 6

Is there a way to associate cells to look at values for each employee and add all the cells for the month?

Thanks,

Thomas
