sql server reporting services:
I have a report that gives me a total of the items on each invoice - the
thing is, it reports multiple invoices (even over 100 of them)
How can I add up each of the Page totals for a Full total (=Sum(??????))
Ideas?

it's the 2nd argument of the SUM function; what scope do you want to
add things

I would make a top-level group by and group on that
