Provider error: Type mismatch *grrrr*

Jeg har dette kodestykke:

case \"save\"
    call connect()
SQL = \"select Mestbl.thread_id as objekt2, Mestbl.isChecked as objekt3, Mestbl.mesbody as objekt4, Mestbl.subject as objekt5, Mestbl.mesdate as objekt6, Mestbl.forumID as objekt7, Mestbl.thread_parent as objekt8, Mestbl.Userid as objekt9, Myforums.forumname as objekt10, Myforums.forumid as objekt11 from Mestbl, Myforums\"   
    RS.Open sql, Conn, 3, adLockOptimistic
    mesbody=request.form(\"mesbody\")
    forumid=request.form(\"forumid\")
    subject=request.form(\"subject\")
    mailme=request.form(\"mailme\")
    \'htmlencode so people can post code
    mesbody=Server.HtmlEncode(mesbody)
    subject=Server.HtmlEncode(subject)
    \'insert br when user do
    mesbody = Replace(mesbody, vbCrLf, \"<br>\")
    rs.addnew
    rs(\"object2\")=0
    rs(\"object3\")=mailme
    rs(\"object4\")=mesbody
    rs(\"object5\")=subject
    rs(\"object6\")=now()
    rs(\"object7\")=forumid
    rs(\"object8\")=0
    rs(\"object9\")=session(\"User_id\")
    rs(\"ip\")= Request.ServerVariables(\"REMOTE_ADDR\")
    rs.update
    call close()

hvor jeg henter data fra forms, samt et forumid fra en select..

Jeg får hele tiden denne fejl, og kan ikke komme videre..
