Titolo: modificare Order e Where in una quey cambiando 2 Select

Ciao a tutti,
    sono un neofita di ASP e non so come risolvere alcuni problemi. Ho
realizzato con DreamWeaver (lo so dovrei scrivere da solo, ma sono un
pivellino) una pagina asp che, collegata ad un database,
visualizza una griglia che suddivide in più pagine.
    Ora vorrei apporre a questa due SELECT che cambiando i valori mi
modificano i risultati della query: il primo SELECT da collegare al WHERE
della Query, il secondo all'ORDER.
    Ossia vorrei fare un query simile a "SELECT * FROM Tabella WHERE Nazione
= '" & Nazione & "' FROM Database ORDER BY " & OrdinaPer.
    Come posso fare? Penso di dovere aggiugere un form e scrivere qualcosa
di
simile a <form action="pagina.asp" method="POST"> e Nazione =
Request.form("Select").
    Mi potete suggerire dove posso trovare qualche esempio che mi possa
aiutare o (meglio e ne sarei arci-grato) dare un ritocco al codice?
    Non sono proprio a secco di VBscript. Scrivo in VB, per cui per ora mi
trovo nella condizione di leggere ma di non sapere ancora scrivere cose
evolute.
Grazie per l'attenzione,
Francesco

A dire il vero il mio Reply era più lungo... non capisco perchè si sia 
troncato.
Riporto, riproviamo
---------------
Ussignur, son centinaia di righe, diversi loop e una fracassina di
variabili INUTILI.
Non oso metterci le mani.
Mi spiace, ma io no.
Col tempo che perdi a capire come fare questo e quello dentro a quel
ginepraio, hai già rifatto il tutto decentemente a mano.
E' questo, che ti invito a fare. Se poi hai problemi, scrivi qui, io ti 
aiuterò di sicuro.
