Forums Scripts & Popups help with queue/line system for twitch

so far i got the !join, !findme, and !listdel commands and script to work, but the !next 3 or !next 7 commands aren't working. when i type either of those commands, it shows "0 still on the list. next 0 names:" when there are names in the list currently. did i make a mistake somewhere? :0
