Summing up values in a report

[Guest]

I have been having a lot of trouble trying to create a grand total on a
report. My Report looks like this..........

date Quantity ProductName ProductPrice
=([Quantity]*[ProductPrice])

I would like to total the =([Quantity]*[ProductPrice]) column to show an
invoice total at the bottom of the page, any ideas how to do this?

Try
=Sum([Quantity]*[ProductPrice])
