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.
