Choosing a value using multiple tables unsolved

Hi!

I've got a new system to pick a car in my game, and it uses some tables. Here are the tables I have:

creators = {
            "roblox",
            "rauluss1",
            "others"
}

carsroblox = {"ModBlueCar",
    "ModGreenJeep",
    "ModPoliceCar",
    "ModRedTruck",
    "ModSchoolBus",
    "ModSportsCar"}

carsrauluss1 = {"ModJumper",
     "ModGrandpaCar",
     "ModTaxi",
     "ModTraveller",
     "ModPartyCar",
     "ModRetro",
     "ModMonster",
     "ModBeetle",
     "ModKart"
}

carsothers = {"ModQuantum",
    "ModDarkHorse",
    "ModDominaytor",
    "ModSpeedaru"
}

Those are all my tables. Right, so I want to pick a car out of here with 2 variables set with some nice scripts.

The 2 numbers are defined as these:

table = number1.Value
car = number2.Value

So to pick the car what I am CURRENTLY doing is this:

chosentable = "cars"..creators[table]
chosencar = chosentable[car]

So in one line that is basically this:

"cars"..creators[table][car]

This returns the following error:

attempt to concatenate field '?' (a nil value)

What am I doing wrong?

You are generating a string where you want a table.
This code

chosentable = "cars"..creators[table]

returns a string like "carsrauluss1". Note that this string does not represent your table named carsrauluss1. It is just a string. So, in effect, what you are attempting here is something like this:

"carsrauluss1"[3] --attempt to index a string. This returns nil.

An alternative approach is this

local cars = {
    {
        "ModBlueCar",
        "ModGreenJeep",
        "ModPoliceCar",
        "ModRedTruck",
        "ModSchoolBus",
        "ModSportsCar"
    },
    {
        "ModJumper",
        "ModGrandpaCar",
        "ModTaxi",
        "ModTraveller",
        "ModPartyCar",
        "ModRetro",
        "ModMonster",
        "ModBeetle",
        "ModKart"
    },
    {
        "ModQuantum",
        "ModDarkHorse",
        "ModDominaytor",
        "ModSpeedaru"
    },
}

local table = number1.Value
local car = number2.Value
chosencar  = cars[table][car]
