Changing a Player's Skybox Locally not working?

Ok, so here's my current issue.

In my game I have 3 separate scripts, where if you're within a certain range of a coordinate, it changes your Skybox and some lighting variables, and if you go out of range of it then it sets the players back to the first Skybox they had.They are all local scripts found under the StarterGUI folder, which - in my knowledge - meant that the changes will only be seen by the LocalPlayer.

First Script:

local player = game.Players.LocalPlayer
local radius = 3000


while true do
	if player:DistanceFromCharacter(Vector3.new(53.007, -103.993, 32.019)) < radius then
    		print("Player is within radius")
		script.Parent.AreaChange.Disabled = false
		wait(1)
	else
		print("Player is out of range")
		script.Parent.AreaChange2.Disabled = false
		wait(1)
	end
end

Second Script (AreaChange):

skych = game.Lighting.Sky

if skych.SkyboxBk == "http://www.roblox.com/asset/?version=1&id=1013852" then
	print("Already set to sky")
	script.Disabled = true
else
	skych.SkyboxBk = "http://www.roblox.com/asset/?version=1&id=1013852"
	skych.SkyboxDn = "http://www.roblox.com/asset/?version=1&id=1013853"
    skych.SkyboxFt = "http://www.roblox.com/asset/?version=1&id=1013850"
    skych.SkyboxLf = "http://www.roblox.com/asset/?version=1&id=1013851"
    skych.SkyboxRt = "http://www.roblox.com/asset/?version=1&id=1013849"
    skych.SkyboxUp = "http://www.roblox.com/asset/?version=1&id=1013854"
	game.Lighting.Ambient = Color3.fromRGB(117, 78, 0)
	game.Lighting.FogColor = Color3.fromRGB(152, 76, 0)
	game.Lighting.FogEnd = 500
	wait(1)
	print("Script Disabled")
	script.Disabled = true
end

The third script (AreaChange2) is essentially the same as AreaChange, save that it uses different Skybox URL's. (I'm using the while loop method as that's the only method I fully comprehend atm so I added the if statement in the second and third scripts)

Now to the heart of the issue. So whenever it's used in a game with 2 or more people playing, and 1 person is within range while another is out of range, it flips back and forth between the Skyboxes, as though it was a global function instead of a local one. This leads me to ask two questions: 1) Is there an error in my script? and 2) Do the Skybox and Lighting Classes only function as global classes instead of local ones?

I think you have to use rbxassetid:// instead of https:// im not really sure
