I am receiving an error message (...could not execute SQL statement...)when I try to run a report with an average of a field. I have a query that calculates turnaround time between 2 dates using the DateDiff function. My query runs fine and the report runs fine as well. I am trying to get an overall average of the turnaround time but when I include that field in the Report Footer section I get the error message. I have many other reports that perform the same average and run fine. Any solution to this problem???
