Have you set up a return value from your sub-report?

This report is designed to show student through puts for a specific qualification(programme). each programme consists of various modules. We need to calculate a figure for enrolments on certain criteria namely the total number of enrolments (broken down by gender and returned from a subreport) and the weighting (Credit Value) of the module in the programme. My problem field is the total for all modules. I need to add each of the enrolment calculations.The Total for the Calculated fields is in a variable Name: FTE Male Total Value Class Name: java.lang.Double Calculation: Sum Expression: Credit Value * Male enrolment Initial Value Expression: 0 Inrement Type: Module Code Reset Type: Programme This field is in the summary band of the report and the evaluation time is set to Band. I still am not able to get the correct total for this calculation

I have been staring at this report for the past 2 days and looking all over the internet for a solutiuon and i have lost track on how many different things I have tried. I am using Jaspersoft Studio ver 6.3.1 I have a report with 2 subreports. There are cetain parameters passed to the subreports in order for them to produce certain values from a seperate database. The results of the calculations in the subreports is returned to the main report. In the details section of the main report various calulatins are performed. I need to add up the calculations and produca a total. Irrespective of what I the result for "FTE Male Total" appears as a null My main report is <?xml version="1.0" encoding="UTF-8"?><!-- Created with Jaspersoft Studio version 6.3.1.final using
