because i needed similar data, the first thing i did was built a query with the necessary data. using the 'query builder' i adjusted the query that the report is based on in order to display the desired results. i inserted a chart based on the query that the report is based on. i 'linked' a field from the chart to a field in the report. i review the report and the chart displays NO data, but when i clear out the linked fields then data appears. the point for linking the fields is to display data that corresponds to the grouping set up on the chart. any advise whould be appreciated.
