Using variable inside a table reference?

I am trying to refer to a subtable

if table.subtable1.state then
    do something
end

And I want to refer to subtable1 using a variable passed by an above function.

local function(KEY)
    if table.KEY.state then
        do something
    end
end

But it seems to always try and access the table literally as table.key (which doesn't exist). How do I do this?

Instead of table.key which will access literally "key", use table[key]. Since table.key == table["key"], you have to use the brackets.

There's something wrong in your function:

local function(key)

has to be

local foo = function(key)

or

local function foo(key)

Not really wrong per say, a function without a name is simply an anonymous function. Although in this case he dosen't appear to be calling it or using it as an argument, so it is somewhat pointless. Probably just meant as an example though.

Ok, I founded it confusing at first… But oh well…
