array undefined

Jeg har brug for nogle andre øjne til at se denne kode igennem. Den melder arrundv undefined. arrundv bliver fyldt med 0,0,0,0. har tjekket.

undv = request.querystring("undv")
st = request.querystring("st")
fo = request.querystring("fo")
tr = request.querystring("tr")
vote = "" & undv & "," & fo & "," & tr & "," & st & ""

arrvote = split(vote,",")

set klb_rec = objConn.execute("select * from klb where navn='" & session("klb") & "'")

arrundv = split(klb_rec("undv_point"),",")
arrst = split(klb_rec("st_point"),",")
arrfo = split(klb_rec("fo_point"),",")
arrtr = split(klb_rec("tr_point"),",")

tilstande = "godt, rimelig, daarlig, slem"
arrtilstand = split(tilstande,",")
andm = "undv, st, fo, tr"
arrandm = split(andm,",")

for t = 0 to 3


for i = 0 to 3
if arrvote(i) = arrtilstand(i) then

ttt = execute("arr" & arrandm(t) & "")

arr = cint(ttt)

execute("arr" & arrandm(t) & " = " & arr + 1 & "")
end if
