Update tekst felt med en form

Hvordan opdatere jeg et tekst felt med en for jeg har prøvet sådan her:

men det virker ikke

<%
Const adOpenKeyset = 1
Const adLockOptimistic = 3
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open "PROVIDER=MSDASQL;DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" & Server.MapPath("../../databaser/rf_it.mdb") & ";UID=admin;PWD=;"
    Set rs = Server.CreateObject("ADODB.RecordSet")
    strSQL = "SELECT * From helpdesk where id=" & Request.Querystring("id")"
    rs.Open strSQL, Conn, adOpenKeyset, adLockOptimistic
        rs.AddNew
    rs("comment") = Request("comment")
        rs.Update
    rs.Close
    Set rs = Nothing
Conn.Close
set Conn = Nothing

response.write ("<meta http-equiv=""refresh"" content=""0;URL=sendt.asp"">")
