Hello Irewell, "When I run the report I get this error. at java.lang.Thread.run(Thread.java:595) net.sf.jasperreports.engine.JRRuntimeException: Invalid type + java.lang.String for parameter A used in an IN clause; the value must be an array or a col lection." It caused by Multiple options, so if you used the Single option with the syntax: "where $X{IN,table.value,AA}", it was wrong. Maybe you should try to use like this: where $P{Parameter} = '#string' Hope It's helpful
