What I would like to do is add up hours shown within specific columns or
ranges on multiple timesheets. But here's the tricky part, to add up only
those cells that have all the same number (i.e. job no.)in a different column
within that same row.
Example: One worksheet
Job Hours
601 8
602 16
601 4
704 11
408 6
602 7

Now to add up hours for each job no. on another totals worksheet:
Job Total Hours
408 6
601 12
602 23
704 11

While at the same time having the cells on the total worksheet linked to the
source, so if I change or clear the hours cell or the job no. cell in the
source range, the totals reflect it.
Is there a way to do this? Please help.
