Did try to clear the fields after the first user logs in, ie Set Field of edit boxes to ""?
Would I do that in the script, or. . .?
This would be a script. And the fields would probably best be defined as fields with global storage. Since (in a hosted file), different users can't see the data entered into a global field by another user and the data thus entered isn't retained when the file is closed using a global field may be all you need to do. (This depends on details of your database design.)
