1) I am using a parameter called $P{Term} for the main report query. My sql expression is: SELECT term, gender_name FROM table WHERE term = $P{Term} GROUP BY term, gender_name 2) I am using multiple cross tabs and would like to use subdatasets. I need to pass the same parameter($P{Term}) to the subdataset. I am not sure how do I do that ?. My sql expression for the subdataset is: SELECT term, class_level FROM table WHERE term = $P{Term} AND class_level ='X' GROUP BY term, class_level Note: I tried to add the parameter)$P{Term}) to the cross tab by..a) right clicking on the crosstab b) cross tab properties c) under sub dataset properties > parameters tab d) clicked on add e) selected $P{Term} as default expression and name 'term' But it does not recognize the parameter....says unknown parameter 'term' Please help me on this. Thanks in advance
