I think you may need to give more information on the database structure and what you are trying to achieve.

From your example it looks like you want to display the same data several times (not sure why you would want to do that) then have a summary at the bottom. If that is what you want you would only be able to do it using several subreports.

If it's not the same data the report should be easily done by using groups:

SUBAREA (a,b,c) being the group header subtotal being the group footer and total being the report footer.
