How I change property of GUI with another script?

I have 2 script 1.(game.StarterGui.ScreenGui.Frame.ChickenMan.Script)-change team script

`local player = script.Parent.Parent.Parent.Parent.Parent
Frame = script.Parent.Parent
local gui = game.StarterGui.ScreenGui.TeleportButton

script.Parent.MouseButton1Click:connect(function()
gui.Visible = true
player.Team = game.Teams:FindFirstChild("ChickenMan")
player.Character.Humanoid.Health = 0
Frame.Position = (UDim2.new(0.5,0,-0.5,0))
game.Workspace.Teleport.RemoteFunction:InvokeServer()
end)`

2.(game.StarterGui.ScreenGui.TeleportButton.LocalScript)- teleport script

 local disabled = false
local player = script.Parent.Parent.Parent.Parent

script.Parent.MouseButton1Click:connect(function()
if disabled == false then
disabled = true
script.Parent.BackgroundColor3 = Color3.new(217, 0, 0)
game.Workspace.Teleport.RemoteFunction:InvokeServer()
wait(3)

disabled = false
end
end)

in first TeleportButton.visible = false i want to set TeleportButton.visible = true in script1 but my script isn't work ,what wrong in my script Can you help me,pls thank

What seemed to be the problem is this variable you stored. local gui = game.StarterGui.ScreenGui.TeleportButton

People tend to do this same kind of mistake, they use the service StarterGui when it does nothing at all but to only 'serve' (PlayerReplicated) the players every child of the StarterGui into the players' PlayerGui. So any GuiObject inside the StarterGui will be PlayerReplicated into the Player's PlayerGui

Therefore, your variable should be local gui = player:WaitForChild("PlayerGui")

he got a point in that but if u want to access the same thing as ur trying to access in ur script then u should change local gui = game.StarterGui.ScreenGui.TeleportButton to local gui = game.Players.LocalPlayer:WaitForChild("PlayerGui").ScreenGui.TeleportButton

that will access the local players screen and the exact same part of the screen as u tried to access in ur own script
