Thank you for the reply, Jason. That's the screen I've been using, but as I said, each time I add "age," once for the minimum and once for the maximum, it just uses the name of the database column "age" for both.
Can I edit the label for each age, so that I have "min age" and "max age" both searching on the column "age" through the DataAssist interface or do I have to dig into the HTML?
