spgID = Request.Form("spgID")

Response.Redirect "forum_reply.asp?id=" & spgid & "&error_code=1"

converted_date = now           

Set Conn = Server.CreateObject("ADODB.Connection")
DSN = "DRIVER={Microsoft Access Driver (*.mdb)}; "
DSN = DSN & "DBQ=" & Server.MapPath("../../db/clubrace.mdb")
Conn.Open DSN

strSQL = "Insert into reply ("
  strSQL = strSQL & "ReplyPoster, "

  strSQL = strSQL & "'" & replyid & "', "
  strSQL = strSQL & "'" & spgid & "')"
Conn.Execute(strSQL)

Conn.Close
Set Conn = Nothing
%>

jeg får følgende fejl med denne kode:

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E07)
[Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression.
/clubrace/forum_reply_funk.asp, line 29

linie 29 er:
Conn.Execute(strSQL)
