Why is my image button working perfectly fine in Studio, but doesnt work in servers?

Hi, I made a image button, in starter gui. When I was in studio the image button worked perfectly fine, but when I went to a test server, the image button wasnt doing anything when I clicked it.

why?

Here is my script in the image button

local player = game.Players.LocalPlayer
local character = player.CharacterAdded:wait()


local lore = player.PlayerGui.ChooseCharacter.Background.Zeus.Lore.TextLabel
local gui = player.PlayerGui.ChooseCharacter
local God = player.PlayerGui.ChooseCharacter.God
local button = player.PlayerGui.ChooseCharacter.Background.Zeus

button.MouseButton1Click:Connect(function()
	gui.Background.Visible = false
	game.StarterPlayer.EnableMouseLockOption = true
	lore.Visible = false
	God.Value = "Zeus"
	
	character.UpperTorso.CFrame = CFrame.new(182, 0.5, 39)  
end)

If you're using a LocalScript to handle the GUI stuff (which you have to), then changing EnableMouseLockOption = true won't actually have any effect to the server meaning it won't replicate to other clients due to FilteringEnabled. To fix this you need a RemoteEvent located in ReplicatedStorage and a Server Script located in ServerScriptService.

Local Script (just added on to what you had)

local player = game.Players.LocalPlayer
local character = player.CharacterAdded:Wait()
local Event = game:GetService("ReplicatedStorage").RemoteEvent -- add a remoteevent object to replicated storage

local lore = player.PlayerGui.ChooseCharacter.Background.Zeus.Lore.TextLabel
local gui = player.PlayerGui.ChooseCharacter
local God = player.PlayerGui.ChooseCharacter.God
local button = player.PlayerGui.ChooseCharacter.Background.Zeus

button.MouseButton1Click:Connect(function()
    gui.Background.Visible = false
    lore.Visible = false
    God.Value = "Zeus"
    Event:FireServer()
end)

Server Script

local Event = game:GetService("ReplicatedStorage").RemoteEvent -- get event

Event.OnServerEvent:Connect(function(Player)
	game.StarterPlayer.EnableMouseLockOption = true
	Player.character.UpperTorso.CFrame = CFrame.new(182, 0.5, 39)  
end

If this doesn't work or you are confused let me know.

you can only use localplayer in a localscript. (assuming script is a child of the button) try on the local script

script.Parent.Activated:Connect(function(player)

script.Parent.RemoteEvent:FireServer()
end)

create a new remote event under the same parent as the script then create a new regular script

script.Parent.RemoteEvent.OnServerEvent:Connect(function(player)
local character = player.CharacterAdded:wait()

local lore = player.PlayerGui.ChooseCharacter.Background.Zeus.Lore.TextLabel
local gui = player.PlayerGui.ChooseCharacter
local God = player.PlayerGui.ChooseCharacter.God

    gui.Background.Visible = false
    game.StarterPlayer.EnableMouseLockOption = true
    lore.Visible = false
    God.Value = "Zeus"

    character.UpperTorso.CFrame = CFrame.new(182, 0.5, 39)  
end)
