I'm trying to acsess 'Buy_Gui' but it says it's not a valid member even though it is??

It's inside of a folder called 'Shop' (and it has been loaded in aswell) local script:

local Shop_Button = script.Parent
local Player = game.Players.LocalPlayer
local Player_Gui = Player:WaitForChild('PlayerGui')
local Cam = workspace.CurrentCamera
local Shop_Cam = workspace:WaitForChild('Shop').Cams.Cam
local Input = game:GetService("UserInputService")
local Set_Tool = game.ReplicatedStorage:WaitForChild('RemoteEvents').Shop:WaitForChild('Set_Tool')
----
Shop_Button.Activated:Connect(function()
    local Fade_Gui = Instance.new('ScreenGui',Player_Gui)
    Fade_Gui.Name = 'Fade_Gui'
    local Frame = Instance.new('Frame',Fade_Gui)
    Frame.Position = UDim2.new(0.46, 0,0.42, 0)
    Frame.Size = UDim2.new(0, 100,0, 100)
    Frame.BackgroundTransparency = 1
    Frame.Size = UDim2.new(0, 1918,0, 1076)
    Frame.Position = UDim2.new(0, 0,0, 0)
    Frame.BackgroundColor3 = Color3.fromRGB(255, 201, 138)
    for i = 1,35 do
        Frame.BackgroundTransparency = Frame.BackgroundTransparency -0.05
        wait(0.01)
    end
        Cam.CameraType = Enum.CameraType.Scriptable
    repeat wait() until Cam.CameraType == Enum.CameraType.Scriptable
    Cam.CFrame = Shop_Cam.CFrame
    wait(0.5)
    for i = 1,35 do
        Frame.BackgroundTransparency = Frame.BackgroundTransparency +0.05
        wait(0.01)
    end
    Fade_Gui:Destroy()
    local Current = "Stick"
    Set_Tool:FireServer(Current)
    ----
    local Buy_Gui = Instance.new('ScreenGui',Player_Gui)
    Buy_Gui.Name = 'Buy_Gui'
    Buy_Gui.Parent = Player_Gui.Shop
    local Buy_Button = Instance.new('ImageButton',Buy_Gui)
    Buy_Button.Name = 'Buy_Button'
    Buy_Button.BackgroundTransparency = 1
    Buy_Button.Position = UDim2.new(0, 257,1, 253)
    Buy_Button.Image = "rbxassetid://3881950533"
    if Input.KeyboardEnabled == true then
        Buy_Button.Position = UDim2.new(0, 542,1, 524)
        Buy_Button.Size = UDim2.new(0, 167,0, 93)
        Buy_Button:TweenPosition(UDim2.new(0, 534,0, 503),"Out","Quad",1)

    elseif Input.TouchEnabled == true then
        Buy_Button.Size = UDim2.new(0, 152,0, 85)
        Buy_Button:TweenPosition(UDim2.new(0, 257,0, 253),"Out","Quad",1)
    end
    Buy_Button.Activated:Connect(function() --(FROM HERE)
        local Buy_Stick_Remote = game.ReplicatedStorage:WaitForChild("RemoteEvents").Shop.Buy_Stick
        ----
        Buy_Stick_Remote:FireServer() --Remote
    end)
end)

Server Script:

game.ReplicatedStorage:WaitForChild('RemoteEvents').Shop.Buy_Stick.OnServerEvent:Connect(function(player,Current)
    print("Server Request accepted.")
    --Variables--
local PlayerGui = player:WaitForChild('PlayerGui')
local Buy_Button = PlayerGui.Shop.Buy_Gui --Cant' acsess
local Current_Tool = player:WaitForChild('Backpack').Current_Tool
----
end)

Output: Buy_Gui is not a valid member of Folder
