How to change a leaderscore value after an event?

I'm trying to add a player win after all the spawns of the other doom spires have been destroyed

Tested, no result

Pretty sure the error line is Wins.Value=Wins.Value+1

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
  
  end
  
  end
  
  end
  
  end
  
  end
  
  end)
