Hi Ben and thank you for the advice and apologies for the lack of
details. In my HTML page I call the first perl script:

ajaxRequest.open("POST", "http://127.0.0.1/cgi-bin/ajax/kba-search.pl",
true);

which populates my select lists. Then I need to capture the user choice
(say a book title) so I can pass it to another Perl script to return the
data about that choice.

How do I capture that data? In Perl or JavaScript? Once I have that then
I can take your suggestion and use it in a GET or POST.
