Game pass script doesn't work, with no reason as to why?

Okay, so I've created a script to inject a Localscript into the players body with the coding being --

game.Players.PlayerAdded:connect(function(player) player.CharacterAdded:connect(function(character) script.Gamepasses:clone().Parent = character end) end)

this part works fine, I am just giving every detail.

Next, I inserted a local script named "Gamepasses" (as stated above) with the following code --

local cashvip = 254637214
local orbitalvip = 254911738


function hascash(player) -- checks to see if the player owns your pass
    return game:GetService("MarketplaceService"):PlayerOwnsAsset(player, cashvip)
end
function hasorbital(player) -- checks to see if the player owns your pass
    return game:GetService("MarketplaceService"):PlayerOwnsAsset(player, orbitalvip)
end

game.Players.PlayerAdded:connect(function(plr)
    if hascash(plr) then
     local sparkles = Instance.new("ParticleEmitter")
sparkles.Parent = game.Players.LocalPlayer.Character.Torso
sparkles.Texture = ("http://www.roblox.com/asset/?id=243891919")
sparkles.Rotation = NumberRange.new(0,90)
sparkles.RotSpeed = NumberRange.new(1,8)
local Color1 = Color3.new(0,255,0)
local Color2 = Color3.new(0,85,0)
sparkles.Color = ColorSequence.new(Color1,Color2)
sparkles.VelocitySpread = 30
sparkles.Speed = NumberRange.new(5,8)
sparkles.Size = NumberSequence.new(0.5,0.6,0.5,0.6,0.5)
sparkles.Lifetime = NumberRange.new(1)
sparkles.Rate = 50
    end
if hasorbital(plr) then
game.Players.LocalPlayer.Character.Humanoid.Walkspeed = 20
game.Players.LocalPlayer.Character.MaxHealth = 125
game.Players.LocalPlayer.Character.Health = 125
end

if game.Players.PlayerAdded.IsInGroup(2587858)then
 local fire = Instance.new("Fire")
 fire.Parent = game.Players.LocalPlayer.Character.Torso
 fire.Color = Color3.new(0,0,0)
 fire.SecondaryColor = Color3.new(0,0,0)
end
end)

Essentially, what I intended the script to do was check whether or not the player had the cash vip or orbital vip game passes. If they had the cash vip, green sparkles are inserted into their torso

if they have the orbital vip, their walkspeed becomes 20, and their health becomes 125.

additionally, if they're in the group, they're supposed to have white fire inserted into their torso

However, none of this works, and the output gives 0 reason as to why. It says there are no errors in the script, it just... doesnt work!
