Subreport in details section of main report.

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.

The only way to total values generated by a subreport is to use a "Shared Variable".

SetGrandTotal - Formula in sub report
WhilePrintingRecords;
Shared numberVar GrandTotal;
GrandTotal := GrandTotal + {Table.Field};

DisplayGrandTotal - formula in Main Report
WhilePrintingRecords;
Shared numberVar GrandTotal;
GrandTotal;

You will also need a Formula that initializes the shared variable. Place it in the
Report Header section or a Group Header section to reset it back to 0 for each group.
WhilePrintingRecords;
Shared numberVar GrandTotal:=0;
