Or you could get fancy and use a hidden frame which pulls the information
from the database (via an Action of course!) in 1) - thus avoiding the
annoying reload.

>------------------------------------------------------------------------------------------------------------------------|
There are 2 ways to go about this:
1) use an onchange() handler in your select-A that submits the new
value and retrieves the corresponding values for select-B everytime
there's a change;
2) pre-load all possibilities and use javascript to change the values
of select-B that depends on A. This option is practical only for small
amounts of combinations of data.
I've personally used option 2 before. Check out:
