I need to group by every week's workdays, such as August 12-16, August 19-23, August 29-Sept 2, etc. I do have a date field in my data, but for some weeks it is blank and when the grouping is done, it doesn't seem to list weeks when it was not used. How do I get my primary group for the report to be generically every week and then get the dates in my date field to show under the correct week? Your help would be much appreciated. Thanks.
