Hi all,

I have a list of several hundred jobs. Each job has a unique JOB ID number
which is in column B. For each job, there may be between 1 and 15 rows,
depending on the number of employees that worked that job. Each employee
would have their own row, and the JOB ID number appears on each row. The
number of hours each employee spent on a particular job is in column F.

I am trying to create a formula that will look at each JOB ID number
starting in cell B2, and add the contents of all cells in column F for that
unique JOB ID number. Then the process would start over when the next JOB ID
number is found.

Here is the layout:

A Employee Name
B Job ID Number
C Job Description
D Phase ID
E Phase Description
F Duration

Data starts in row 2

Sample report:

A2 B2 C2 D2 E2 F2

Juan ... 2646 ... ABC Co. ... 10 ... Delivery ... 7.0
Alex ... 2646 ... ABC Co. ... 10 ... Delivery ... 4.0
Juan ... 2655 ... XYX Co. ... 10 ... Delivery ... 6.5

So I would like to have this formula add up the hours of 7.0 and 4.0 for job
2646, and do the same for each and every new JOB ID number.

I am using Excel 2007 with XP Pro.

Anyone have an idea?

Thanks!
