Thank you June and all the other forum members. I changed the one symbol and tried the code on my sample DB. The first time it changed the "Current" field from No to Yes so I changed the ">" to "<" in the code and it worked. I added several more entries with various " DuesDue" dates. Now when I open the DB the corrections are made. Hallelujah!
The code in "OnLoad" is CurrentDb.Execute "UPDATE Members SET [Current] = Date() < DuesDue;" Don't know why it has to be < but now it changes the "Current" field from Yes to No (Checked to Unchecked).
