I have a subreport in the details section of the main report, the sub report calculate the total weight for each detail line on a delivery note. At the bottom of the total weight coloum I want the grand total for all the items on the delivery note. When I insert the the grand total or subTotal option on the subreport, it gives me the grand total for each detail line and not for all the lines together.

What am I doing wrong?
Plz help.
