What I do is this:

Where I set up the form, for the first combo box, I fill it using
the results from the query:

"SELECT * FROM countries"

and name that combo box "country_name".  I set an event on
this combo box to be "OnChange=form.submit();"

For the second combo box, I use the query:

"SELECT * FROM cities WHERE country=\"$country_name\""

So the combo box will be empty the first time into the page but
each time they select a new country, it gets filled appropriately.

I have some checks to determine where the form submission is
coming from so I know whether or not to actually process the
