Peter,
Thanks for your comments. While I toy around with dhtml, I'll give them careful
thought. I have to admit, I'm bothered myself by the stuttering movement across the
page.

That could be a bit of a problem, but it's possible. You could write an
"onSubmitJobNumber" script that would query the database (using the id) for the job
description, and layer the response into the page (also called data binding). You'd
be restricting yourself to IE 4.0+ though, as it's the only browser currently able to
perform the task using dhtml. Flat fields as well as ODBC access to the relational
are permitted, and it could be implemented effectively in an intranet. You'd still be
taxing the server with the query, but you wouldn't need to reload the entire page (the
job description could be programmed to "magically" appear below the submission form).
Of course, if you're not already geared toward the MS product, you're talking about a
lot of work for relatively little effect. But I think you already know that.
