Stò creando con l'aiuto di Dreamweaver e un database in access un elenco di aziende suddivise per categorie e citta.
sono circa 2000 .
Ora ho realizzato una pagina default.asp che con un form esegue la ricerca e va alla pagina "azienda.asp" dove in relazione alla scelta della categoria e della citta deve visualizzare le aziende scelte..
MENTRE IL
codice - pagina "default.asp":

Provo e riprovo ma mida sempre lo stesso errore
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC Microsoft Access Driver] Syntax error in string in query expression 'qAziende LIKE 'ABBIGLIAMENTO TECNICO' AND Citta LIKE 'OLBIA - (OT) ORDER BY CATEGORIE, Citta'.
/aziende/aziende2.asp, line 20. ( la stringa "RsAziende.Open(" )
Giro e rigiro ma nn riesco a trovare la stringa giusta perchè funzioni.
Ringrazio fin da ora per un Vostro Cortese aiuto..a capirci qualcosa..
