I have a subreport that has a volume field that is summed in the subreport. The subreport exists in a detail section of a main report, which has three groups. The detail belongs to the inner most group. The summary for the inner most group can be done and displayed in the subreport footer, which corresponds to the inner most group of the main report. How can I summarize this data at the group level of the outer two groups in the main report using Crystal Reports 7.0? Any help would be appreciated.
