My leaderboard works in studio, but not on a live server. How do I fix?

I'm making a military themed game that has the ranks saved in the game code. and I have this leaderboard script:~~~~~~~~~~~~~~~~~

game.Players.PlayerAdded:connect(function(p)
local stats = Instance.new("StringValue")
stats.Name = "leaderstats"
stats.Parent = p

local rank = Instance.new("StringValue")
rank.Name = "Rank"
rank.Value = "REC"
local reg = Instance.new("StringValue")
reg.Name = "Regiment"
reg.Value = "No-Reg"

--ranks--

PVT = {}
LCPL = {}
CPL = {}
SGT = {}
SSGT = {}
WOC2 = {}
WOC1 = {}
LT = {}
CPT = {}
MAJ = {}
LTCOL = {}
COL = {}
BRIG = {}
MAJGEN = {}
LTGEN = {}
GEN = {}
FM = {"wexabite"}

--regiments--

RIFLES = {}
RGG = {}
SAS = {}
AAC = {}
PARAS = {}
ETS = {}

for i=1, #RIFLES do
    if RIFLES[i] == game.Players.LocalPlayer.Name then
        reg.Value = "RIFLES"
    end
end
for i=1, #RGG do
    if RGG[i] == game.Players.LocalPlayer.Name then
        reg.Value = "RGG"
    end
end
for i=1, #SAS do
    if SAS[i] == game.Players.LocalPlayer.Name then
        reg.Value = "SAS"
    end
end
for i=1, #AAC do

    end
end
for i=1, #WOC2 do
    if WOC2[i] == game.Players.LocalPlayer.Name then
        rank.Value = "WOC2"
    end
end
for i=1, #WOC1 do
    if WOC1[i] == game.Players.LocalPlayer.Name then

    end
end

~~~~~~~~~~~~~~~~~ The problem is: It works flawlessly in studio, but not in game :/ Any help? Am I doing something wrong?
