form update med for next funktion

Hey E

IIS5.0, IE7.0, ASP3.0, access2000

hvorfor kan jeg ikke få denne kode til at virke?

if request.ServerVariables("REQUEST_METHOD") = "post" then
    response.Write("test")
else ' post %>
    <form action="default.asp?mode=flyvisupdate" method="post" name="updateall">
<%    hvilken = "3;5;8;9;11;13;14;15;"
    hvilken = Split(hvilken,";")
    for i = 0 to ubound(hvilken) - 1
        strSQL = "SELECT * FROM EH101_status WHERE aircraft_id="&hvilken(i)
        rs_custom strSQL,3,""  'start db
        for each x in rs.fields
            if x.name <> "aircraft_id" then
                editAircraft = editAircraft & (x.value) & ";"
                DBName = DBName & (x.name) & ";"
            end if
        next
        rs_end()

        editAircraft = Split(editAircraft,";")
        DBName = Split(DBName,";")%>

<input class="input" type="text" value="<%=editAircraft(0)%>" style="width:88px;">
<br>
<%next%>
<input type="submit" style="position:absolute; top:30px; left:50px;">
<%
end if ' post
end if ' mode %>

fejlen er : Type mismatch

i linjen: editAircraft = editAircraft & (x.value) & ";"

hvad mangler jeg ?
