Gui wont work in roblox player but will work in studio and i cant find out why?!

I have a gui script but when i use it in studio is fine but in the player it wont work

local frame = script.Parent.Parent.Frame
local toggle = false
script.Parent.MouseButton1Click:connect(function()
	if toggle == false then
frame:TweenPosition(UDim2.new(0.37, 0.04, 0.001, 0), "Out", "Back", 3)
       script.Parent.Text = "<"
       toggle = true
       else
   frame:TweenPosition(UDim2.new(-0.002, -200, 0.001, 3), "In", "Back", 3)
       toggle = false
       script.Parent.Text = "<"
   end
end)

Weird, same happened to me and at least 20 guys more, it is all working correctly, what I will recommend.

For experimented developers: check if there's another script interfering with the work of this one What I did: submit everything on models to Roblox and create a new game adding everything again, I won't recommend to do that if your game was hard to do or is fully released, because it will delete all visits and and all that stuff (this solution worked to me)
