So i have this code:

local Table = {}

function tick()
local index = Table[0]


This code outputs nothing. I specifically need to get whatever the last item put in the array is. I'm essentially trying to create a First in Last Out stack but I'm stuck here. Thanks.

Lua is 1-indexed. Because tables are much more dynamic than arrays, you can put data into slot 0 if you really want to, but table.insert() won't do that for you.

If you wanted to print the last item inserted into the array, then you could use print(Table[#Table]) instead (#Table gives the highest index in the table before a nil value is encountered). If you wanted to knock that value out of the table at the same time (so that repeat calls work their way down your "stack"), you could instead use print(table.remove(Table)).
