Hello I'm using Jasper Studio 6 to design my reports and I have come up against problem that is driving me mad! My report contains a number of fields (contractName, contractNumber, contractDescription etc.) and a table based on a dataset containing 2 fields (contractNumber, contractDocuments). When I preview the report, the contract documents are shown on all records, not the one contract record they belong to. How do I stop that happening? e.g. contract1 table is blank, contract 2 table contains the document entries? Thanks for any help! Richard S UPDATE I have fixed the issue now, by adding the parameter to the main report and another to the dataset query, mapping them together and a fair bit of jiggery pokery! Thanks for your help and pointing me in the right direction.
