i got error unable to cast to dictionary at line 10?

probably cuz of roblox dev tutorials not being good

they didn't tell me that much of what goes where

and yes it is a gui i am trying to tween

wait(1.2)

local TS = game:GetService("TweenService")

local loading_screen = script.Parent
local loading_type_selected = loading_screen.load_type_selected.Value
local loading_types = loading_screen.logo.loading_types

local brick1_tween_info = TweenInfo.new(1, Enum.EasingStyle.Linear, Enum.EasingDirection.Out, 0, false, 1)
local brick1_tween = TS:Create(loading_types.bricks.brick_1, brick1_tween_info, Vector2.new(0.5, 0.95))

function game_loading()
    if loading_type_selected == "bricks" then
        brick1_tween:Play()
    end
end

function check_if_loaded()
    if not game:IsLoaded() then 
        game.Loaded:Wait()
        game_loading()
    end

    if game:IsLoaded() then
