Hi Sherman, I tried having a boolean expression for PrintWithExpression properties in both field header and field value. Also Checked the option "Remove line when blank" for both field header and field value. And also Checked the option "Blank when null" for field value. Still I get the error: com.jaspersoft.jasperserver.api.JSExceptionWrapper: Unknown column name : DEP_UUID ... ... Here DEP_UUID is the column name which is not present in the query resultset. I want to have this column because I want to show it for a differnt query based on user input. Could you please give me some help on this and let me know where can I get help on this. Thanks, Subha Post Edited by Subha Epari at 12/15/08 10:37
