i've found two articles relating to your requirement in the MSDN KB. I'm manually typing the links and if doesn't work search by the KB number. You can even modify the second KB article to make it reusable.

search number: Q102890 Running totals in BROWSE command

search number: Q114253 Summing a field in a database
