Round Not Working?

This is a simple script that makes rounds. Unfortunately, when the Alien dies, nothing happens. The if statement is supposed to make all the players beside the alien get points when this happens, but it never does. Script Analysis gives me no errors, nor the output!

local localtimer = roundtime
while localtimer > 0 do     
    wait(1)
    localtimer = localtimer - 1
    message.Value = "Round Time Left: (" .. localtimer .. ")"

    activeplayers = {}

    -- local player = players[math.random(1, #players)]

        for _, player in pairs(game.Players:GetPlayers()) do
         local humanoid = player.Character:WaitForChild("Humanoid")
         if humanoid and humanoid.Health > 0 then
             table.insert(players, player)
    for _, players in pairs(activeplayers) do
        if player then
            if player.Character then
            if player.Character.Humanoid.Health > 0 then
                if player.Character:FindFirstChild("activetag") then
                    table.insert(activeplayers, player)
                end
            end
        end
    end 
end
        end
    end 




    alienactive = true

    --local player = players[math.random(1, #players)]

        local playersin = {}    


for _, player in pairs(game.Players:GetPlayers()) do
  local humanoid = player.Character:WaitForChild("Humanoid")
  if humanoid and humanoid.Health > 0 then
    table.insert(playersin, player)
  end
end     



    if alien.Character.Humanoid.Health > 0 then
        alienactive = true

        local function remove_value(Table, Value)
    for i,v in pairs (Table) do
        if v==Value then
            table.remove(Table,i)
        end
    end
end

 remove_value(playersin, alien) 

    if localtimer == 0 then
        message.Value = "Time's Up! It's a Draw!"
        break
    end


print(#playersin)
        if #playersin == 0 then
            message.Value = "The Alien Has Won!"
                alien.leaderstats.Wins.Value = alien.leaderstats.Wins.Value + 1
                alien.leaderstats.Points.Value = alien.leaderstats.Points.Value + 300
                break
        end
        if alien.Character.Humanoid.Health == 0 then
        alienactive = false
        message.Value = "The Alien Has Lost!"
        print ("ALL IS LOST!!!")

for _, player in pairs(#playersin) do
  local humanoid = player.Character:WaitForChild("Humanoid")
  if humanoid and humanoid.Health > 0 then
    player.leaderstats.Points.Value = player.leaderstats.Points.Value + 200
    player.leaderstats.Wins.Value = player.leaderstats.Wins.Value + 1
  end
end 
break
    end
