Type mismatch.....

Får en fejl når dette script køres:

<%
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open "DRIVER={Microsoft Access Driver (*.mdb)};DBQ="&Server.Mappath("db/db.mdb")
id_cw = Request.QueryString("id")
sql = "select * from upcomming_cws where id= " & id_cw & ""
set cw_info = Conn.Execute(sql)


if Request.querystring("won") = ("clan_one") then
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open "DRIVER={Microsoft Access Driver (*.mdb)};DBQ="&Server.Mappath("db/db.mdb")
sql = "SELECT * from clans WHERE ID=" & cw_info("clan1")
Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open sql, Conn, 1, 3

    rs.update
    rs("won") + 1
    rs.update

Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open "DRIVER={Microsoft Access Driver (*.mdb)};DBQ="&Server.Mappath("db/db.mdb")
sql = "SELECT * from clans WHERE ID=" & cw_info("clan2")
Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open sql, Conn, 1, 3

    rs.update
    rs("lost") + 1
    rs.update
   
   
Response.Redirect("delete_upcw.asp?delete=" & request.QueryString("id"))
end if
%>

Den siger "Type mismatch: '[String: "won"]'

hvad er der galt?
