access error 0x80040E10, pleaz Help !!

I have a Page validating password, as I start building it
I've tried to test it, and when the validating page runs I
get this error :

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E10)
[Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.
/test/passord/registrering/validering.asp, line 15

The Error line 15 is the execute sql line, but I can't see
the point of telling me that there are too few parameters !!

Can someone look at my code below and tell me what's wrong !!




CODE STARTS :

<%
' set up connection
Set Conn = Server.CreateObject("ADODB.Connection")
DSN = "DRIVER={Microsoft Access Driver (*.mdb)}; "
DSN = DSN & "DBQ=" & Server.MapPath ("database.mdb")
Conn.Open DSN

  User = Request.Form("txtUser")
  Pass = Request.Form("txtPass")

response.write(user)

' get from database & compare
strSQL = "Select * From personer Where bruker = " & user
Set rs = Conn.Execute(strSQL)

if rs("passord") = Pass then
session("abbonement") = rs("type")
session("brukernavn") = user
Conn.Close
Set Conn = Nothing
response.write ("<script>parent.location='../karidreitisenga/memi.asp'</script>")
else
response.redirect"../main.asp"
end if

Conn.Close
Set Conn = Nothing
%>
