Hi, I need some help in building some sums in my report... please :-) (Using iReport 4.0.2) I have two groups in my report, in the footer of the inner group I'm calling a subreport, which is calculating a sum, prints it, returns it within a variable. I can print this variable in the same band using evaluationtime band (only for testing). Now I want to add this value to a sum for the outer group. I'm trying for hours... the output is always null. My way is another variable, calculation is sum, variable expression is the first variable, reset- and increment type I've tested in each possible combination... also I tried $V{variable1}.add($V{variable2}) as expression... no success.... Any idea for a solution...? Thanks a lot! Christof
