sql and ms access query: some records works other not..

Ciao

i'm a newbie, i seldom update an access mdb which is quiried from a web site. Inside that mdb there are users and passwords to access to a private area.

After the latest mdb update users and pws don't work as before. Some works other not and I cannot understant what logic is behind it.

I'm posting query sql code to find an help. I hope somebody could give me an hand.

Bye



codice:
<%
'Dimension variables
Dim adoCon 'Database Connection Variable
Dim strCon 'Holds the Database driver and the path and name of the database
Dim rs 'Database Recordset Variable
Dim strAccessDB 'Holds the Access Database Name
Dim strSQL 'Database query sring
Dim strUserName 'Holds the user name
Dim url 'Holds the url

Response.Buffer=True

'If the session variable is False or does not exsist then redirect the user to the unauthorised user page
If Session("blnIsUserGood") = False or IsNull(Session("blnIsUserGood")) = True then
'Redirect to unathorised user page
Response.Redirect"unauthorised_user_page.htm"
End If

'get the strUserName variable
strUserName = Request.QueryString("name")

'Check the database to see if user exsits and read in there password
'Initialise the strAccessDB variable with the name of the Access Database
strAccessDB = "users"

'Create a connection odject
Set adoCon = Server.CreateObject("ADODB.Connection")

'Database connection info and driver
strCon = "DRIVER={Microsoft Access Driver (*.mdb)};uid=;pwd=quicelapassword; DBQ=" & Server.MapPath(strAccessDB)

'Set an active connection to the Connection object
adoCon.Open strCon

'Create a recordset object
Set rs = Server.CreateObject("ADODB.Recordset")

%>


HERE THERE IS HTML CODE THEN

codice:
<%
strSQL = "SELECT * FROM tblUsers WHERE tblUsers.UserID ='" & strUserName & "'"

'Query the database

rs.Open strSQL, strCon

'Response.Write strQry & "<br><br>"


set codi=rs.Fields("UserID")
set desc=rs.Fields("Password")
set url=rs.Fields("Link")
set nom=rs.Fields("NOME")
set cog=rs.Fields("COGNOME")
nom_cog = "" & nom & " " & cog

url_comp = "HERE THERE IS THE PATH" & desc &".pdf"



if rs.EOF then
%>
<tr><td colspan="3" class="norbold" align="center">Nessun link disponibile</td></tr>
<%
else
while not rs.EOF
%>
