#1

So I trying to make my ui overal for console and a bit tweenings but on the selection api with the dropdown it not select the first TextButton in the dropdown it wierdly says that fyncontroler is an invalid Gui object but it should be an valid Gui object since it is a text button I tried with printing it and it prints the correct ui element this is the script

local drop = script.Parent.dropdownframe
local button = drop:WaitForChild("fyncontroler") -- the button 
local dropimage = script.Parent.edrop
local framee = script.Parent.Parent.Parent.Parent.a
--local frames = script.Parent.Parent.Parent.Parent.Parent.Parent.backframe.frames
local UIS = game:GetService("UserInputService")
local GS = game:GetService("GuiService")

local open = false
script.Parent.MouseButton1Click:Connect(function()
    
    if open == false then
        --if UIS.GamepadEnabled then
            --GS:Select(script.Parent.dropdownframe)
            GS.SelectedObject = button -- here
            print(script.Parent.dropdownframe.fyncontroler)
            --GS.SelectedObject = drop.fyncontroler
        --end
        framee.thumb.Visible = false
        framee.x.Visible = false
        dropimage.Rotation = 180
        drop.Visible = true
        --frames.Visible = false
        open = true
    elseif open == true then
        --if UIS.GamepadEnabled then
    GS.SelectedObject = script.Parent
        --GS:Select(script.Parent.Parent.Parent.Parent.Parent.Parent.Parent.frame2.controles.scroller.a.jump.jump)
        --end
        framee.thumb.Visible = true
        framee.x.Visible = true
        dropimage.Rotation = 0
        drop.Visible = false
        --frames.Visible = true
        open = false
    end

end)

It should toggle the dropdown frame and what disable the frame should be disabled if you click an button in the dropdown too and runs an function

The second is the tweenings it stops the intaire script from running if I tween all children from a frame it is a script with near 200 lines so I only place te loop

for i,v in frames:GetChildren() do
        if v:IsA("ImageLabel") then
            
            local SlidingEfectCN = TS:Create(v,TI,SizeCurrent)
            SlidingEfectCN:Play()
            v.Visible = false
        end
    end
    nextframe.Visible = true
    local SlidingEfectNN = TS:Create(nextframe,TI,SizeNew)
    SlidingEfectNN:Play()
    for i,v in buttons:GetChildren() do
        if v:IsA("TextButton") then
            v.Visible = false 

        end
    end

Error I get

Unable to cast to Dictionary

What do you want to archive
I will that the tweenings should work and the dropdowns first button be selected on console

#2 
--tweens--

local TS = game:GetService("TweenService")

local SizeNew = UDim2.fromScale(1.012,0.044)
local SizeCurrent = UDim2.fromScale(1.012,1.006)

local TI = TweenInfo.new(
	0.5,
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.InOut,
	0,
	true,
	0
)

--===================================================================--
-- next navigation --

local function navigatenext()
	script.Parent.Active = false
	buttonback.Active = false
	buttonnext.Active = false
	for i,v in frames:GetChildren() do
		if v:IsA("ImageLabel") then
			--local fram1 = v
			local SlidingEfectCN = TS:Create(v,TI,{Size = SizeCurrent})
			print(v)
			SlidingEfectCN:Play()
			--task.wait(0.5)
			v.Visible = false
		end
		
		nextframe.Visible = true
	local SlidingEfectNN = TS:Create(nextframe,TI,{Size = SizeNew})
	SlidingEfectNN:Play()
	end
	
	
	for i,v in buttons:GetChildren() do
		if v:IsA("TextButton") then
			v.Visible = false 

		end
		script.Parent.Active = false
	buttonback.Active = false
	buttonnext.Active = false
	end
	--task.wait(0.5)

for the tweenings it works bug it first flash I think it makes invisible visible frames and then tweens actually first it plays tween 1 then switch the frames than play tween two
