Hi Neil,

If your app can tolerate Javascript (i.e., require it), then Ajax is
probably your best bet.  Take a look here:

Grab a copy of the JWPCookbook.  In it is a recipe called Dynamic
Double-Select, which is exactly what you want.  You should be able to take
that example as-is and use it in your own app without much trouble.

If your are Javascript-averse though, your only real choice is a two-step
approach, i.e., show the page with the first dropdown and a button which
submits the form.  Then display the page with the second dropdown and two
buttons, one to continue on and one to go back and select another option
from the first.
