Scripting help with tables!?

--variables
local player = game:GetService('Players').LocalPlayer
local replicated = game:GetService('ReplicatedStorage')
local class = player:WaitForChild('bin').Class

--table
local classes ={
    [1]="Swordsman";
    [2]="Gunner";
    [3]="Mage";
    [4]="Berserker";
    [5]="Barbarian";
    [6]="Archer";
    [7]="Assassin";
    [8]="Conjurer";
    [9]="Enchanter";
    [10]="Elementalist";
    [11]="Gladiator";
    [12]="Ninja";
    [13]="Pirate";
    [14]="Paladin";
    [15]="Priest";
};

fetch = function (parent, query)
    for i, child in ipairs(parent:GetChildren()) do
        --loop through the parent "argument"
        if child:IsA('Model') or child:IsA('Folder') then
            -- if child is a "Model" or "Folder" 
            if child.Name:upper() == query:upper() then
                -- if "Name" property matches "query" argument
                return child
            end
        end
    end
end

class.Changed:connect(function (property)
    if property == 'Value' then
        -- if the changed property is the class' `Value` property
        for index, value in ipairs(classes) do
            -- loop through table `classes`
            if class[property] == index then
                -- if value of `class` equals `index`

                print(index, value)
                script.Parent.Text = value
                -- set text to `value`

                folder = fetch(replicated, tostring(index))
                print(folder:GetFullName())
            end
        end
    end
end

I used the Changed event instead of your while loop because it would be much more efficient considering that it only fires when the object/instance is changed instead of continually.
