Sub report Problem

[tanvirtonu]

Somebody pls tell me how to use two subreports in another report.I mean-I have a report which has two subreport elements and these two reports use different queries with no parameter passing between them.But when I made it this way I got "no document" message.I made it this way bcos I want to show my report the following way-

Item___________Amount

Wood____________300

Oil_____________500

Total___________800

 

If I use a master report and a subreport for Total I get the following format-

Item___________Amount

Wood____________300

Total___________800

 

Oil_____________500

Total___________800

Can anybody tell me how to do it pls?
