Hello, I am trying to re-use a value held in my report - which has been calculated in a sub-report. Its a percentage total that I want to use to draw the pie chart. Is something like this possible: select 'Top 10', $P{Usage_Percentage} from dual UNION select 'Rest', 100-$P{Usage_Percentage} from dual (I dont want to re-execute queries for the pie chart) Ireports does not seem to like having Parameters in the select statement. Can anyone please advise, would be very appreciated. Thank You, Jaxa.
