Someone help me to fix the SkyBox for planets?

local Skyboxes = {
    Earth = {
        SkyboxBk = "http://www.roblox.com/asset/?id=225469345" -- Id here
     
    }
}
Earth = {
        SkyboxDn = "http://www.roblox.com/asset/?id=225469349" -- Id here
        
   }
Earth = {
        SkyboxFt = "http://www.roblox.com/asset/?id=225469359" -- Id here
        
 }
Earth = {
        SkyboxLf = "http://www.roblox.com/asset/?id=225469364" -- Id here
        
 }
Earth = {
        SkyboxRt = "http://www.roblox.com/asset/?id=225469372" -- Id here
        
 }
Earth = {
        SkyboxUp = "http://www.roblox.com/asset/?id=225469380" -- Id here
        
 }
local Input = script.Parent.Ilhas["Earth"] -- This is an example for getting the planet

if Skyboxes[Input] then
game.Lighting.Skybox.SkyboxBk = Skyboxes[Input]["SkyboxBk"]
game.Lighting.Skybox.SkyboxDn = Skyboxes[Input]["SkyboxDn"]
game.Lighting.Skybox.SkyboxFt = Skyboxes[Input]["SkyboxFt"]
game.Lighting.Skybox.SkyboxLf = Skyboxes[Input]["SkyboxLf"]
game.Lighting.Skybox.SkyboxRt = Skyboxes[Input]["SkyboxRt"]
game.Lighting.Skybox.SkyboxUp = Skyboxes[Input]["SkyboxUp"]
end

Does not work this script, to put skybox on the planets. like you enter the planet skybox change to the different skybox on the planet, it didn't work.
