I have a worksheet set up as a monthly record of hours worked:
Example
Date Job No. Hours worked
01/02 2167 4
2000 2.5
2412 1.5
(total C1:C3) 8

This runs throughout the month; each day is calculated and the summary of
the hours worked appears at the end, using (9,C4:Cn), e.g 160.

On the next page of the same worksheet, I need the total of hours worked
during the month for each job, e.g:

Job No. Hours
2000 22
2167 14
2412 2
etc ...
Total .....160

Is there a way to calculate/add up all the hours worked during the month for
each job to enter on Page 2 rather than, as I do now, going through each day
and writing down each job and the hours worked on it.
