Hi Richard. To achieve the sorting you desire, I suggest you use a numeric calculated parameter (e.g. "Task Sort") and combine some IF statements with some math that convert the Priorities -- e.g. IF(Project Priority = 'Critical', 5000,IF(Project Priority = 'High', 4000,...)) + IF(Task Priority = 'Critical', 500,IF(Task Priority = 'High', 400,...)). The result would give Task Sorts such as 5500, 5400, 5100, 4400, 4300, etc, by which to Sort (and Group, for that matter). Regards, Doug Doug Den Hoed - AtAppStore
