I have nothing in the record source properties for either the report or the sub-report.
I will try to define my problem a little better:
I have created a count query the returns four "buckets"
I then took this query and created a bar chart report utilizing the chart wizard.
Once I created the report I put it into a Summary Report via the subreport option, I did this because I am trying to provide a report that management can quickly look at.
I also get an occasional chart that has no data. I can rerun the report, with no modification to anything, and the chart will populate properly again. I am not sure if this is realated or not.
