error object variable not set

[Piero]

With this simple programs (using aspdb FREE on my local installation or aspdb PRO on ISP) i always get the same error on calling .aspdbfree or .aspdbpro

aspDB error '800a005b'

Object variable or With block variable not set

/adg/nazioni.asp, line 5

the program is

<% set dbAsp=createobject(&#34;aspdb.free&#34
dbasp.dbdat=&#34;xxxxx,yyyy,sa&#34;
dbasp.dbsql=&#34;Select DESCRIZIONE from ADG_NAZIONI where ID_AZIENDA=1 order by descrizione&#34;
dbasp.aspdbfree
%>

I try with .recordset, . dbdsn but error remains
I am using sql server 7, ado 2.1 etc..

Many thanks
