Tom,
Much debate in our house about this one. As the man (Rick Curtis, he IS the man) said, code your access queries IN access, then use that query as your source for the SQl window in UD. In access setup a query and in the date field in the criteria row type in >=Date()AND<=(Date()+8). That should be a dynamic way of getting all your dates whenever they are to be available or whatever from today to 8 days hence.
Have fun
M
