macOS Adium AppleScript

Hi, so i'm sure you're all sick of these type of requests. I am trying to make an applescript for adium to promote something to everyone in my contact list. But before you judge horribly, I want it to only message each person once! Almost as if i were to msg them myself! So i've made this script (as i'm a real newbie in applescript) but it doesn't work: Can anyone see the errors? :/


tell application "Adium"
activate
tell application "Adium"

set the_file to "/Users/craaig/windzo.txt"

-- opens the txt file and reads off the list of windows already messaged

set foo to (open for access (POSIX file the_file))

set oldwindows_txt to (read foo for (get eof foo))

set oldwindows to every paragraph of oldwindows_txt

close access foo

-- compares the list from the file and the current open windows
-- if anyone new appears, it puts it into an array.

set currentwindows to id of every chat

repeat with x from 1 to count of items of currentwindows
set n to item x of currentwindows
if n is not in oldwindows then set end of peoples to n
end repeat

set loopbacktofile_list to oldwindows & peoples
set loopbacktofile to (loopbacktofile_list) as text

open for access the_file with write permission
set eof of the_file to 0
write (loopbacktofile) to the_file starting at eof
close access the_file

-- sending messages

repeat with x from 1 to count of items of peoples
set n to item x of peoples

send (first chat whose id is (n)) message ("test" as Unicode text)

end repeat
end tell
end tell

Any help would be greatly appreciated!! 🙂
