- create a subreport that returns a value. - assign the value in the main report to variable A - add a sum variable in the main report over A Tried to solve the problem using different evaluation times (report, now, auto, band) neither made a difference. (page, group, and column didn't make sense to me.) Code:database table `test` (id,v1):(1,10),(2,20),(3, NULL),(4,40),(4,50)
