How to include subtotals for a database when printing !

[M Imran Buhary]

I have to print a large database with several columns of figurs, running in
to number of pages. Is there any possibility to include a subtotal for
selected colimns at each page break automatically? The page break keeps on
changing with data addition or removal so I dont want to insert subtotalevery
time the page braek changes to a different place.
