Groups with Subtotals and GrandTotal

[phmckeever]

Hello,

I have what I think is a simple report. It is an access report with the
following fields:

WRF Number
Date Received
Date Completed
Turn_Around (Formula field: diff between Date Completed and Recieved)

I need to be able to group by month and do subtotals on the Turn_Around
field, with a grand total at the end on the Turn_Around field.

Can someone help me. Can't get the 'Sorting and Grouping' thingy to work.
