Hi,
Field extractor returns table of messges if there's more then one,
but you have to assign table to your variable rather than first
element so it should look something like:
local isup_messages = { isup_extractor() }
for i, isup_single_msg in ipairs(isup_messages)
do
-- process your single isup message here
end
regards
