fejl i SQL/if

hej eksperter...

jeg har denne kode:

if session("brugerID") = rs("bruger_id") then
'vis ikke stemmefunktion
else
  sql = "SELECT * FROM tjek WHERE bruger_id=" & Session("brugerID") & " and artikel_id=" & Request.Querystring("id")
  set rs = conn.execute(sql)
  If adoRec.EOF Then
response.write "<tr><td colspan='2'><hr size='1' color='#000000'></td></tr>"
response.write "<tr><td valign='top' colspan='2'><h2><center><form action='rate.asp?id=" & rs("id") & "' method='post'>1&nbsp;<input type='radio' name='1' checked value='1'>2&nbsp;<input type='radio' name='1' value='2'>3&nbsp;<input type='radio' name='1' value='3'>4&nbsp;<input type='radio' name='1' value='4'>5&nbsp;<input type='radio' name='1' value='5'></h2></center></td></tr>"
response.write "<tr><td colspan='2'><center><input type='submit' value='Stem'></center></td></tr>"
response.write "</table>"
  else
response.write "</table>"
  end if
end if

og få denne fejl:

Microsoft VBScript runtime error '800a01a8'
Object required: 'adoRec'

hvad er der galt ?

mvh.
