My script works for the first player who joins, but doesn't for the second player?

Notes;

1. This is Normal script

2. This is in server script service

here is my code;

local teamForFirstGuy
local BlueSpawn = game.Workspace:WaitForChild('BlueTower').BlueSpawn
local RedSpawn = game.Workspace:WaitForChild('RedTower').RedSpawn
local AOP = game.ReplicatedStorage:WaitForChild('AmountOfPlayers')
local BlueEffect = game.Lighting:WaitForChild('Blur')
local W = 0.07

local function AddPlayer(plr)
    AOP.Value = AOP.Value + 1

    local Stats = Instance.new('Model')
    Stats.Name = 'PlrStats'
    Stats.Parent = plr


    local Team = Instance.new("StringValue")
    Team.Name = "Team"

    if teamForFirstGuy then
        Team.Value = teamForFirstGuy == "Blue" and "Red" or "Blue"
    else
        Team.Value = math.random() < .5 and "Blue" or "Red"
        teamForFirstGuy = Team.Value

        Team.Parent = Stats

        plr.CharacterAdded:Connect(function(char)
               if Team.Value == 'Red' then
                wait()
                char:WaitForChild('HumanoidRootPart').CFrame = BlueSpawn.CFrame
            else
                wait()
                char:WaitForChild('HumanoidRootPart').CFrame = RedSpawn.CFrame
            end
        end)    
    end
end
game.Players.PlayerAdded:Connect(function(player)
    AddPlayer(player)
end)

The problem is probably here;

if teamForFirstGuy then
        Team.Value = teamForFirstGuy == "Blue" and "Red" or "Blue"
    else
        Team.Value = math.random() < .5 and "Blue" or "Red"
        teamForFirstGuy = Team.Value

        Team.Parent = Stats

        plr.CharacterAdded:Connect(function(char)
               if Team.Value == 'Red' then
                wait()
                char:WaitForChild('HumanoidRootPart').CFrame = BlueSpawn.CFrame
            else
                wait()
                char:WaitForChild('HumanoidRootPart').CFrame = RedSpawn.CFrame

Because the first player gets's teleported to the correct spawn, the second player spawns in ROBLOX default spawn. So maybe I gotta change it so that if the player is on team blue then the next player is on team red? Please help!
