PLEASE NOTE: report designed using iReport 4.5 and deployed in JasperServer 4.5 by linking the iReport designer to the server using Repository Navigator. I have also created the input control thru the Repository Navigator section. I couldnt figure out how to extract values from the CheckBox input control. Input Control type: Multi Select List of Values (Check Box) Parameter Name: P_Quater Parameter Value: Q1, Q2, Q3, Q4 My report has 4 columns displaying values that belong to 4 quaters sample as shows bleow Q1 Q2 Q3 Q4 =============== 01 02 03 04 01 02 03 04 01 02 03 04 01 02 03 04 What I am trying to achieve is If I select Q1, Q2 from my input control screen I want to see only the first 2 columns in the report Q1 Q2 =============== 01 02 01 02 01 02 01 02 My CheckBox parameter value from the input contol comes in as [Q1,Q2] How do I check the values by extracting the values as Q1 and Q2 so that I can do the following (P_Quater == "Q3")?true:false in "Print When Express" to supress the column Thanks for your help in advance.
