Hi, I posted this on the jasperserver forums but thought may be this is more relevant here. Sorry for the double posting. Is it possible to implement some logic based on input control values (parameters)? Here is an example of what I'd like to do: 1. For my report, I would like to provide some flexibilily in selecting the date range. There are options such as "Last Day," "Last Week," "Last Month," and "Generic Date Range." I'd probably implement this as a "Single-select List of Values (Radio)" input control (where each option might simply have a numeric value). Please let me know if there are other, better options. 2. Now based on what user selected for the above, I'd like to tweak the WHERE clause for the query accordingly. How can I do this? Additionally, if user selects "Generic Date Range," I'd like to display 2 additional date fileds. I'm not sure if this kind of auto hide/show functionality is available. Any help is appreciated. Thanks, Vijay
