Will anyone help me with my script??[SOLVED!!!!]

So I've already asked to help with this script before, but now there is 1 problem. It works in studio, but it glitches the freak out in a real server. This is the script:

-----------------------------------------------

local player = script.Parent.Parent.Parent.Parent
local M = script.Parent
local listbkg = M.ListBkg
local stopp = M.StopPic

local repp = M.RepeatPic
local musicl = M.MusicList
local next = M.Next
local less = M.Less
local more = M.More
local drag = M.Dragger
local dragtext = M.DragText

local musiclist = {}
local musicmodel = script.Parent.Parent.Music
local music = musicmodel:children()
for i,v in pairs(music) do
v.Looped = false
v.PlayOnRemove = false
table.insert(musiclist,v:clone())
end
musicmodel:remove()
local musiclistbuttons = {}
for i,v in pairs(musiclist) do
local ng = Instance.new("TextButton",M)
ng.Position = UDim2.new(0, 0, 0, 20) + UDim2.new(0,0,0,13*i)
ng.Size = UDim2.new(0, 200, 0, 13)
ng.BackgroundTransparency = 1
ng.BackgroundColor3 = Color3.new(0/255,0/255,0/255)
ng.BorderColor3 = Color3.new(255/255,255/255,255/255)
ng.TextColor3 = Color3.new(255/255,255/255,255/255)
ng.Font = "ArialBold"
ng.FontSize = "Size10"
ng.Visible = false
ng.Text = v.Name
ng.Name = v.Name
table.insert(musiclistbuttons,i,ng)
ng.MouseButton1Click:connect(function()
if ng.BackgroundTransparency == 1 then
changesong(musiclist[i])
end
end)

end

listbkg.Size = UDim2.new(0, 120, 0, 20) + UDim2.new(0,0,0,13*#musiclistbuttons)
