>I have a Main Report with two subreports. The values in the subreports come from different tables than the values in the main report. Is there a way to create a computed field on the main report that adds up certain fields that are on the subreports? Basically (not actual syntax) you would have mainreport.computedfield = subreportA.value1 + subreportB.value2.
