A follow up from Alvaro about Parameter Queries in Excel shows that we have settled this issue amicably! Thank you. I just realized that on Saturday. I had never worked with this command before. I do know how to solve my problem now. Your mail is giving me the certainty of it. I'll tell you just a little bit of what I'm doing. I'm the Maintenance chief at a microcomponents facility. One of my technicians is programming a database to control and manage the preventive and corrective issues. Because that database is just in the first stage, I don't want to make it hard for him, so I decided not to include yet the reporting module in the database, instead I'm consulting it with Excel. You know it is nice for charts. Well, friend, thank you very much for your help. Keep in contact. Well done! DW
