How to change a leaderscore value after an event?

In Server Script Service

 PlayersRequiredToStartAwardingPoints=2

local y=workspace:GetDescendants()

local Wins=player.leaderstats.Wins



for s=1,#y do

if y[s].Name=="Doomspires" then

-- GAME VALUES --

local GVF=Instance.new("Folder")

GVF.Parent=y[s]

GVF.Name="GameValues"

local TF=Instance.new("Folder")

TF.Parent=GVF

TF.Name="Teams"

local TeamsLeftInt=Instance.new("IntValue")

TeamsLeftInt.Parent=GVF

TeamsLeftInt.Name="TeamsLeft"

local k=y[s]:GetChildren()

for o=1,#k do

if not k[o]:IsA("Script") then -- Only make values

if k[o].Name~="GameValues" then

if k[o].Name~="Holder" then

local BCV=Instance.new("BrickColorValue")

BCV.Parent=TF

BCV.Name=k[o].Name

local SpawnVal=Instance.new("IntValue")

SpawnVal.Parent=BCV

SpawnVal.Name="Spawns"

local u=k[o]:GetDescendants()

for h=1,#u do

if u[h]:IsA("SpawnLocation") then

BCV.Value=u[h].TeamColor

SpawnVal.Value=#u[h].Parent:GetChildren()

end

end

end

end

end

end

TeamsLeftInt.Value=#TF:GetChildren()

if y[s]:WaitForChild("GameValues",1):WaitForChild("TeamsLeft",1).Value==1 then -- If 1 team remains then

local e=y[s]:WaitForChild("GameValues",1):WaitForChild("Teams",1):GetDescendants()

for j=1,#e do

if e[j].Name=="Spawns" then

if e[j].Value~=0 then -- ... find that team, whose spawn does NOT have a value of zero

wait(4)

local msg=Instance.new("Message")

msg.Text=e[j].Parent.Name.." TEAM has won the game!"

local p=game.Players:GetChildren()

for q=1,#p do

if #p>=PlayersRequiredToStartAwardingPoints then -- if there's more than 4 people playing then

if e[j].Parent and p[q].TeamColor==e[j].Parent.Value then

Wins.Value=Wins.Value+1

end

end

end

msg.Parent=workspace

script.RegenScriptLocation.Value.Signal.Value=true -- ... regen the map using the Changed function.

return
