Perhaps check these out:Some ways to do a dependent list box are the following:
1) Reload a self-posting form (disadvantage: form has to reload).
2) Send all the data down to the form and let JavaScript do the work (disadvantage: sends all the data to the form).
3) Remote scripting (disadvantage: may have security risks).
4) Hidden frames (disadvantage: complicated).
Updating a Listbox from Another Listbox

Puts the first listbox value into querystring and then reloads the same page.
(Have to download the script.)

Reloads the same page. Has PopulateListBox and RefreshPage subs.
Has demo to test. The demo takes awhile to refresh the page and doesn't put user back where was.
And here is another similar one by same author:
