Hi Peggy:
There's a small issue with that tutorial, in that it tells you that you need to write all that JS code...
That's not exactly true. Under "Custom" in the "Library" palette, there's an option for "Data drop-down list". If you drag that to your form, you can easily populate the list of form elements from a database. I'm working on writing up a small tutorial on how to connect to a MySQL database under Windows.
The code at the end, though it is FormCalc, could also be JS based. I'll be showing that in the tutorial as well.
What other, specific, questions did you have?
Mike
