I’m trying to make a code save system for my game (Using datastore2 if that’s any help), and whenever i try and input a code that exists, I get an error saying ‘Unable to cast value to Object’

code 
local CodeInput = script.Parent.Parent.CodeInput

script.Parent.MouseButton1Click:Connect(function()
	local Code = CodeInput.Text
	if Code == '' then
		print("Code cannot be blank")
		CodeInput.Text = 'Code cannot be blank'
	else
		for i,v in pairs(game.ReplicatedStorage.Codes:GetChildren()) do
			if v.Name == Code then
				game.ReplicatedStorage.RemoteEvents.CheckCodes:FireClient(Code, v)
			else
				script.Parent.Parent.CodeInput.Text = "Code does not exist"
			end
		end
	end
end)

I don’t know what it means and I’ve tried searching for it online. Got nothing. please help. Thanks

For FireClient, the first parameter needs to be the player.
