I am having a problem with my program….
Whenever I try to access an index on it it just returns (ERROR: Index expected, got string)
I'll give a snippet of the code and if I need to post more of it tell me and I will add it.
Whitelist[50] = P
where P is the player to be added and Whitelist is the list of allowed players.
I've tried EVERY single value, it just will not work! :(/>
EDIT: Here's my code:
Thanks for the help.
Now time to add the final thing, and if that works, you won't hear from me again on this post.
Now I'm having a problem with my Wifi Controller (see below's spoiler). It says on line 5 that it's attempting to call nil.
EDIT2: I'm dumb. Fixed the errors and am waiting for thread to close.

I completely spaced out about adding the . It works fine now.That error message means Whitelist is a string. I don't know how or why until you post the code, but it is.
Now time to add the final thing, and if that works, you won't hear from me again on this post.

PS, it's my first time using this thread, so now I know to paste the whole code next time. Thanks for the help!Spoiler
print("Please input username.")
local U = io.input() --It's supposed to wait until someone inputs something here, but that's not happening, so I'm confused
local M = peripheral.find("modem")
M.open(15)
M.broadcast(15,15,{U,"TEST"})
local _,_,_,_,Msg = os.pullEvent("modem_message")
if Msg == "Test Successful!" then
term.setTextColor(colors.green)
print("Successfully validated!")
term.setTextColor(colors.white)
end
while true do
term.clear()
print("Input the command.")
local C = io.input()
M.broadcast(15,15,{U,C})
