Twitch Follower Program Help

Okay so I have this program made by Bacon_Donut that shows you how many followers and vewiers you have on twitch. I'm getting an error that says: twitch:39: attemt to index ? (a nil value). Btw my program is named twitch.

-- This is formatted to fit on a 1x3 wall of Advanced Monitors
-- with an Advanced Computer on the left side.
-- To get this to work you need to edit the streamid variable then run these four commands:

-- label set SomeKindOfNameHere
-- pastebin get 4nRg9CHU json
-- pastebin get vhn1z23v startup
-- startup

-- ChangeLog:
-- Feb 16, 2015 - @CoolAcid
-- Added automatic download of JSON parser
-- Fixed the offline streamer detection
-- Added last follower option

-- Twitch Name of the Streamer
streamid = "Bacon_Donut"


-- SleepTime is how often to grab new data. Set here to one minute.
-- Set it too fast and twitch will flag you for spam
-- and stop giving you data
SleepTime = 60
