Matrix Report - Subtotals

Good moring,
I am working on my first matrix report and trying to add in a total for a
group and rows
Table is as follows:
Account Manager Job Number Jan Sales Feb Sales
Peter J54455 598 60
Peter J65559 500 70
David J76666 400 80
Jane J74445 700 90
I would like to have:
1) a subtotal row when the Account Manager changes.
2) a total for each row.
Example:
Account Manager Job Number Jan Sales Feb Sales Total
Peter J54455 500 60
560
Peter J65559 500 70
570
Total Peter 1000 130
1130
David J76666 400 80
480
Total David 400 80
480
Jane J74445 700 90
790
Total Jane 700 90
790
I know this is inherent in the matrix report, however I have spent hours
trying to figure out and still cannot determine how to achieve both of these
2 things (simple as they may be).
Can anyone help?
Thanks JamesAs an amendment,
I have discovered how to add row total so ignore that part.
As to the subtotal on the Account Manager I still have an issue with that.
I tried right clicking on the Account Manager name and choose subtotal.
However this puts a grand total for all account Managers, not a subtotal for
each account manager. Any ideas'?
