Do you mean that the actions on one dashboard should effect all the dashboards? For the filters to work across dashboards, the same worksheets need to be on each dashboard or multiple actions have to be created, one for each dashboard.
Maybe you can post a sample workbook (twbx file) with a description of the desired outcome?
Nope, I wanted the worksheets contained in one dashboard to filter the other worksheets in the same dashboard. Specifically, I wanted to filter using one worksheet, and then further refine the view by clicking on another worksheet (still in the same dashboard) to further refine the other remaining dashboards. Can't really post a workbook, unless I extract and filter/hide a lot of information (the extract is about 100mb per datasource)...
