~750.I don't think it is a numbers problem as it has generated reports for years plus I created a new file with only 6 names and I had the same problem.Interestingly, after my message to you I retried perhaps half a dozen more times and eventually I could print charts again (and got the ones I needed for now).Now, just before I responded to you I tried and the program wouldn't create a chart (I got the "There is not enough free space on the disk." message again.) ?????
